Justice O’Connor
delivered the opinion of the Court.
Federal habeas relief is available to state prisoners only after they have exhausted their claims in state court. 28 U.S. C. §§ 2254(b)(1), (c) (1994 ed. and Supp. III). In this case, we are asked to decide whether a state prisoner must present his claims to a state supreme court in a petition for discretionary review in order to satisfy the exhaustion requirement We conclude that he must.

In 1977, respondent Darren Boerckel was tried in the Circuit Court of Montgomery County, Illinois, for the rape, burglary, and aggravated battery of an 87-year-old woman. The central evidence against him at trial was his written confession to the crimes, a confession admitted over Boerekel’s objection. The jury convicted Boerckel on all three charges, and he was sentenced to serve 20 to 60 years’ imprisonment on the rape charge, and shorter terms on the other two charges, with all sentences to be served concurrently.
Boerckel of Illinois, raising several issues. He argued, among other things, that his confession should have been suppressed because the confession was the fruit of an illegal arrest, because the confession was coerced, and because he had not knowingly and intelligently waived his rights under Miranda v. Arizona, 384 U. S. 436 (1966). Boerckel also claimed that prosecutorial misconduct denied him a fair trial, that he had been denied discovery of exculpatory material held by the police, and that the evidence was insufficient to support his conviction. The Illinois Appellate Court, with one justice dissenting, rejected Boerekel’s claims and affirmed his convictions and sentences. People v. Boerckel, 68 Ill. App. 3d 103, 385 N. E. 2d 815 (1979).
Illinois Supreme Court. In this petition, he raised only three issues. Boerckel claimed first that his confession was the fruit of an unlawful arrest because, contrary to the Appellate Court’s ruling, he was under arrest when he gave his confession. Boerckel also contended that he was denied a fair trial by prosecutorial misconduct and that he had been erroneously denied discovery of exculpatory material in the possession of the police. The Illinois Supreme Court denied the petition for leave to appeal, and this Court denied BoerckePs subsequent petition for a writ of certiorari. Boerckel v. Illinois, 447 U. S. 911 (1980).
a pro se petition for a writ of ha-beas corpus under 28 U. S. C. § 2254 in the United States District Court for the Central District of Illinois. The District Court appointed counsel for Boerckel, and BoerckePs counsel filed an amended petition in March 1995. The amended petition asked for relief on six grounds: (1) that Boerckel had not knowingly and intelligently waived his Miranda rights; (2) that his confession was not voluntary; (3) that the evidence against him was insufficient to sustain the conviction; (4) that his confession was the fruit of an illegal arrest; (5) that he received ineffective assistance of counsel at trial and on appeal; and (6) that his right to discovery of exculpatory material under Brady v. Maryland, 373 U. S. 83 (1963), was violated.
In an order dated November 15, 1995, the District Court found, as relevant here, that Boerckel had procedurally defaulted his first, second, and third claims by failing to include them in his petition for leave to appeal to the Illinois Supreme Court. No. 94-3258 (CD Ill.), pp. 4-10. Boerckel attempted to overcome the procedural defaults by presenting evidence that he fell within the “fundamental miscarriage of justice” exception to the procedural default rule. See Coleman v. Thompson, 501 U. S. 722, 750 (1991). At a hearing on this issue, Boerckel argued that he was actually innocent of the offenses for which he had been convicted and he presented evidence that he claimed showed that two other men were responsible for the crimes. In a subsequent ruling, the District Court concluded that Boerckel had failed to satisfy the standards established in Schlup v. Delo, 513 U. S. 298 (1995), for establishing the “fundamental miscarriage of justice” exception, and thus held that Boerckel could not overcome the procedural bars preventing review of his claims. No. 94-8258 (CD Ill., Oct. 28, 1996), pp. 14-15. After rejecting Boerekel’s remaining claims for relief, the District Court denied his habeas petition. Id., at 18.
On appeal, the Court of considered one question, namely, whether Boerekel had procedurally defaulted the first three claims in his habeas petition (whether he knowingly and intelligently waived his Miranda rights, whether his confession was voluntary, and whether the evidence was sufficient to support a verdict) by failing to raise those claims in his petition for leave to appeal to the Illinois Supreme Court. The Court of Appeals reversed the judgment of the District Court denying Boerckel’s habeas petition and remanded for further proceedings. 135 F. 3d 1194 (1998). The court concluded that Boerekel was not required to present his claims in a petition for discretionary review to the Illinois Supreme Court to satisfy the exhaustion requirement. Id., at 1199-1202. Thus, according to the Court of Appeals, Boerekel had not procedurally defaulted those claims. Id., at 1202.
We granted certiorari to resolve a of Appeals on this issue. 525 U. S. 999 (1998). Compare e.g., Richardson v. Procunier, 762 F. 2d 429 (CA5 1985) (must file petition for discretionary review), with Dolny v. Erickson, 32 F. 3d 381 (CA8 1994) (petition for discretionary review not required), cert. denied, 513 U. S. 1111 (1995).

Before a federal court may grant habeas relief to a state prisoner, the prisoner must exhaust his remedies in state court. In other words, the state prisoner must give the state courts an opportunity to act on his claims before he presents those claims to a federal court in a habeas petition. The exhaustion doctrine, first announced in Ex parte Royall, 117 U. S. 241 (1886), is now codified at 28 U. S. C. § 2254(b)(1) (1994 ed., Supp. III). This doctrine, however, raises a recurring question: What state remedies must a habeas petitioner invoke to satisfy the federal exhaustion requirement? See Castille v. Peoples, 489 U. S. 346, 349-350 (1989); Wainwrigkt v. Sykes, 433 U. S. 72, 78 (1977). The particular question posed by this case is whether a prisoner must seek review in a state court of last resort when that court has discretionary control over its docket.
Illinois law provides for a two-tiered appellate review process. Criminal defendants are tried in the local circuit courts, and although some criminal appeals (e. g., those in which the death penalty is imposed) are heard directly by the Supreme Court of Illinois, most criminal appeals are heard first by an intermediate appellate court, the Appellate Court of Illinois. Ill. Sup. Ct. Rule 603 (1998). A party may petition for leave to appeal a decision by the Appellate Court to the Illinois Supreme Court (with exceptions that are irrelevant here), but whether “such a petition will be granted is a matter of sound judicial discretion.” Rule 315(a). See also Rule 612(b) (providing that Rule 315 governs criminal, as well as civil, appeals). Rule 315 elaborates on the exercise of this discretion as follows:
“The following, while neither controlling nor fully measuring the court’s discretion, indicate the character of reasons which will be considered: the general importance of the question presented; the existence of a conflict between the decision sought to be reviewed and a decision of the Supreme Court, or of another division of the Appellate Court; the need for the exercise of the Supreme Court’s supervisory authority; and the final or interlocutory character of the judgment sought to be reviewed.” Rule 315(a).
Boerckel’s amended federal habeas petition raised three claims that he had not included in his petition for leave to appeal to the Illinois Supreme Court. To determine whether Boerckel was required to present those claims to the Illinois Supreme Court in order to exhaust his state remedies, we turn first to the language of the federal habeas statute. Section 2254(e) provides that a habeas petitioner “shall not be deemed to have exhausted the remedies available in the courts of the State ... if he has the right under the law of the State to raise, by any available procedure, the question presented.” Although this language could be read to effectively foreclose habeas review by requiring a state prisoner to invoke any possible avenue of state court review, we have never interpreted the exhaustion requirement in such a restrictive fashion. See Wilwording v. Swenson, 404 U. S. 249, 249-250 (1971) (per curiam). Thus, we have not interpreted the exhaustion doctrine to require prisoners to file repetitive petitions. See Brown v. Allen, 344 U. S. 443, 447 (1953) (holding that a prisoner does not have “to ask the state for collateral relief, based on the same evidence and issues already decided by direct review”). We have also held that state prisoners do not have to invoke extraordinary remedies when those remedies are alternatives to the standard review process and where the state courts have not provided relief through those remedies in the past. See Wilwording v. Swenson, supra, at 249-250 (rejecting suggestion that state prisoner should have invoked “any of a number of possible alternatives to state habeas including ‘a suit for injunction, a writ of prohibition, or mandamus or a declaratory judgment in the state courts,’ or perhaps other relief under the State Administrative Procedure Act”).
Section 2254(e) requires only that state state courts a fair opportunity to act on their claims. See Castille v. Peoples, supra, at 351; Picard v. Connor, 404 U. S. 270, 275-276 (1971). State courts, like federal courts, are obliged to enforce federal law. Comity thus dictates that when a prisoner alleges that his continued confinement for a state court conviction violates federal law, the state courts should have the first opportunity to review this claim and proviole any necessary relief. Rose v. Lundy, 455 U. S. 509, 515-516 (1982); Darr v. Burford, 339 U. S. 200, 204 (1950). This rule of comity reduces friction between the state and federal court systems by avoiding the “unseemfliness]” of a federal district court’s overturning a state court conviction without the state courts having had an opportunity to correct the constitutional violation in the first instance. Ibid. See also Duckworth v. Serrano, 454 U. S. 1, 3-4 (1981) (per curiam); Rose v. Lundy, supra, at 515-516.
the exhaustion doctrine is designed to give the state courts a Ml and fair opportunity to resolve federal constitutional claims before those claims are presented to the federal courts, we conclude that state prisoners must give the state courts one Ml opportunity to resolve any constitutional issues by invoking one complete round of the State’s established appellate review process. Here, Illinois’ established, normal appellate review procedure is a two-tiered system. Comity, in these circumstances, dictates that Boerckel use the State’s established appellate review procedures before he presents his claims to a federal court. Unlike the extraordinary procedures that we found unnecessary in Brown v. Allen and Wilwording v. Swenson, a petition for discretionary review in Illinois’ Supreme Court is a normal, simple, and established part of the State’s appellate review process. In the words of the statute, state prisoners have “the right... to raise” their claims through a petition for discretionary review in the State’s highest court. § 2254(e). Granted, as Boerckel contends, Brief for Respondent 16, he has no right to review in the Illinois Supreme Court, but he does have a “right ... to raise” his claims before that court. That is all § 2254(e) requires.
conclusion with two related arguments. His first argument is grounded in a stylized portrait of the Illinois appellate review process. According to Boerckel, Illinois’ appellate review procedures make the intermediate appellate courts the primary focus of the system; all routine claims of error are directed to those courts. The Illinois Supreme Court, by contrast, serves only to answer “questions of broad significance.” Id., at 4. Boer-ckel’s view of Illinois’ appellate review process derives from Ill. Sup. Ct. Rule 315(a) (1998). He reads this Rule to discourage the filing of petitions raising routine allegations of error and to direct litigants to present only those claims that meet the criteria defined by the Rule. Rule 315(a), by its own terms, however, does not “eontro[l]” or “measur[e]” the Illinois Supreme Court’s discretion. The Illinois Supreme Court is free to take eases that do not fall easily within the descriptions listed in the Rule. Moreover, even if we were to assume that the Rule discourages the filing of certain petitions, it is difficult to discern which eases fall into the “discouraged” category. In this case, for example, the parties disagree about whether, under the terms of Rule 315(a), Boerckel’s claims should have been presented to the Illinois Supreme Court. Compare Brief for Respondent 5 with Reply Brief for Petitioner 5.
The better reading of Rule 315(a) is that the Illinois Supreme Court has the opportunity to decide which cases it will consider on the merits. The fact that Illinois has adopted a discretionary review system may reflect little more than that there are resource constraints on the Illinois Supreme Court’s ability to hear every ease that is presented to it. It may be that, given the necessity of a discretionary review system, the Rule allows the Illinois Supreme Court to expend its limited resources on “questions of broad significance.” We cannot conclude from this Rule, however, that review in the Illinois Supreme Court is unavailable. By requiring state prisoners to give the Illinois Supreme Court the opportunity to resolve constitutional errors in the first instance, the rule we announce today serves the comity interests that drive the exhaustion doctrine.
Boerekel’s second argument is related to his first. According to Boerekel, because the Illinois Supreme Court has announced (through Rule 315(a)) that it does not want to hear routine allegations of error, a rule requiring state prisoners to file petitions for review with that court offends comity by inundating the Illinois Supreme Court with countless unwanted petitions. Brief for Respondent 8-14. See also 135 F. 3d, at 1201. This point, of course, turns on Boerekel’s interpretation of Rule 315(a), an interpretation that, as discussed above, we do not find persuasive. Nor is it clear that the rule we announce today will have the effect that Boerckel predicts. We do not know, for example, what percentage of Illinois state prisoners who eventually seek federal habeas relief decline, in the first instance, to seek review in the Illinois Supreme Court.
We acknowledge that the rule we announce today — requiring state prisoners to file petitions for discretionary review when that review is part of the ordinary appellate review procedure in the State — has the potential to increase the number of filings in state supreme courts. We also recognize that this increased burden may be unwelcome in some state courts because the courts do not wish to have the opportunity to review constitutional claims before those claims are presented to a federal habeas' court. See, e. g., In re Exhaustion of State Remedies in Criminal and Post-Conviction Relief Cases, 321 S. C. 563, 471 S. E. 2d 454 (1990); see also State v. Sandon, 161 Ariz. 157, 777 P. 2d 220 (1989). Under these circumstances, Boerckel may be correct that the increased, unwelcome burden on state supreme courts disserves the comity interests underlying the exhaustion doctrine. In this regard, we note that nothing in our decision today requires the exhaustion of any specific state remedy when a State has provided that that remedy is unavailable. Section 2254(c), in fact, directs federal courts to consider whether a habeas petitioner has “the right under the law of the State to raise, by any available procedure, the question presented.” (Emphasis added.) The exhaustion doctrine, in other words, turns on an inquiry into what procedures are “available” under state law. In sum, there is nothing in the exhaustion doctrine requiring federal courts to ignore a state law or rule providing that a given procedure is not available. We hold today only that the creation of a discretionary review system does not, without more, make review in the Illinois Supreme Court unavailable.
claims that he had pressed before the Appellate Court of Illinois, but that he had not included in his petition for leave to appeal to the Illinois Supreme Court. There is no dispute that this state court remedy — a petition for leave to appeal to the Illinois Supreme Court — is no longer available to Boerekel; the time for filing such a petition has long passed. See Ill. Sup. Ct. Rule 315(b). Thus, BoerckeFs failure to present three of his federal habeas claims to the Illinois Supreme Court in a timely fashion has resulted in a procedural default of those claims. See Coleman v. Thompson, 501 U. S., at 731-732; Engle v. Isaac, 456 U. S. 107, 125— 126, n. 28 (1982).
We do not disagree with Justice scription of the law of exhaustion and procedural default. Specifically, we do not disagree with his description of the interplay of these two doctrines. Post, at 853-854 (dissenting opinion). As Justice Stevens notes, a prisoner could evade the exhaustion requirement — and thereby undercut the values that it serves — by “letting the time run” on state remedies. Post, at 853. To avoid this result, and thus “protect the integrity” of the federal exhaustion rule, ibid., we ask not only whether a prisoner has exhausted his state remedies, but also whether he has properly exhausted those remedies, i. e., whether he has fairly presented his claims to the state courts, see post, at 854. Our disagreement with Justice Stevens in this case turns on our differing answers to this last question: Whether a prisoner who fails to present his claims in a petition for discretionary review to a state court of last resort has properly presented his claims to the state courts. Because we answer this question “no,” we conclude that Boerekel has proeedurally defaulted his claims. Accordingly, the judgment of the Court of Appeals for the Seventh Circuit is reversed.
It is so ordered.
