Associate Justice of the Supreme Court of the United States
The President "shall nominate, and by and with the Advice and Consent of the Senate, shall appoint... Judges of the supreme Court." Although the Constitution refers to them as "Judges of the Supreme Court," the title actually used is "Associate Justice," introduced in the Judiciary Act of 1789. Associate justices were traditionally styled "Mr. Justice" in court opinions, but the title was shortened to "Justice" in 1980, a year before the first female justice was appointed.
