Writing in "Rolling Stone" in January 2002, Greg Kot described "If I Needed Someone" as Harrison's "finest tune to date" by 1965. In the same publication, David Fricke included it in his list of the "25 Essential Harrison Performances". Fricke described the track as, variously, a "folk-rock diamond" and "the ultimate compliment" to the Byrds in its "striking blend of cool dismissal ... and crystalline riffing". Writing for "Q" magazine, John Harris recognised "Rubber Soul" as marking Harrison's "first decisive stride forward" as a songwriter, with "If I Needed Someone" suggesting for the first time that he could match the standard of Lennon and McCartney's work. Bruce Eder of AllMusic identifies the song as a "near-classic" written by Harrison during a period when his association with the Rickenbacker guitar had helped define the folk rock sound of groups such as the Byrds. In a 2002 review of "Rubber Soul", for "Mojo", Richard Williams admired the track as "a little gem, an early classic of power pop which lasts not a second too long".
