"She's a Woman" is a song by the English rock band the Beatles, written primarily by Paul McCartney and credited to Lennon–McCartney. It was released on a non-album single in November 1964 as the B-side to "I Feel Fine", except in North America, where it also appeared on the album Beatles '65, released in December 1964. Though it was the B-side, it charted in the US, reaching number four on the Billboard Hot 100 and number eight on the Cash Box Top 100. The song originated in McCartney's attempt to write a song in the style of Little Richard. The lyrics include the first reference to drugs in a Beatles song, with the line "turn(s) me on" referring to marijuana.

"She's a Woman" is mainly in the key of A major, with brief shifts to C-sharp minor, and is in time. Besides its two short bridge sections, the song only uses the chords I, IV and V. The Beatles had one of their earliest experiences with the drug six weeks earlier – smoking with Bob Dylan in New York City during their 1964 North American tour – with Lennon reflecting in 1980 that "[w]e were so excited to say 'turn me on' – you know, about marijuana and all that, using it as an expression". while the first true stereo mix of the song to be released in the US appeared on the 1988 compilation Past Masters, Volume One. The mono mix was subsequently included on the 2009 Mono Masters compilation.

Among contemporaneous reviews, Derek Johnson in the NME described "She's a Woman" as "arresting and ear-catching", and highlighted the track's "pounding beat" and blues-inflected vocal. Billboard predicted an immediate chart hit for both sides of the single and recognised the record as a "gift to Capitol on the group's first anniversary with the label". The UK single release sold 800,000 units within five days and over a million by 9 December. In the US, where five albums and sixteen singles had been released in the first seven months of 1964, the ensuing lull of new Beatles material led to fans highly anticipating the next single's release. The US release sold more than a million copies in its first week. "She's a Woman" became a hit in its own right, mostly on the strength of point of sale requests, peaking at number four on the Billboard Hot 100 and remaining on the chart for nine weeks.

In a retrospective review for AllMusic, Stephen Thomas Erlewine says the song demonstrates the Beatles' ability to "rock really, really hard". MacDonald describes the track as "the most extreme sound the Beatles had manufactured to date". Writing that it is the first Beatles song to feature a high profile bass line, he opines that it foreshadows McCartney's later "striving to get his instrument 'up' in volume, tone, and octave". He further characterises the recording as outré, and groups it with "What You're Doing" and "Eight Days a Week" as one of McCartney's late-1964 recording experiments. Everett writes that his piano playing on the song "[took] his keyboard work to a new level", while describing Harrison's guitar solo as rockabilly in style, heavily influenced by guitarist Carl Perkins. Rolling Stone critic Rob Sheffield opines that the song's "power-chord thud" anticipates the sound of the heavy metal band Black Sabbath.

Spencer calls the song McCartney's "stoned out-take on his Little Richard legacy", and musicologist Alan W. Pollack describes the song as McCartney's "most outrageous vocal performance" since "Long Tall Sally", anticipating that of the 1969 songs "Get Back" and "Oh! Darling". Critic Richie Unterberger counts the cover as among several on the LP that few listeners would have thought possible to arrange into a bluegrass context. In a retrospective assessment coinciding with the album's 1995 CD re-release, Adrea Moed of CMJ New Music Monthly magazine remarked that the playing on the cover displays a "technical virtuosity [that] almost makes you forget [the song’s] origins".

British guitarist Jeff Beck covered "She's a Woman" on his 1975 album Blow by Blow, produced by George Martin. Months earlier, he played the song with the band Upp for the BBC documentary Five Faces of Guitar. Keyboard player Max Middleton suggested the song for the album, having come up with a calypso-like arrangement on his own. Middleton later recalled that "George hated it, but Jeff loved it, so we did it". Beck further altered the arrangement into a reggae instrumental, following the original vocal melody with his guitar, and incorporated a talk box. Mark Kirschenmann of AllMusic describes the arrangement as clever, Reaching number twenty on the UK Singles Chart and number 14 on the UK Airplay Chart in April 1991, the recording immediately preceded a lengthy hiatus from Scritti Politti frontman Green Gartside, who did not return to recording until 1999. Later included on the band's 2011 compilation album Absolute, Terry Staunton of Record Collector magazine describes the track as a "trenchtown jolly-up" cover. bass, piano
