"(I Can't Get No) Satisfaction" is a song by the English rock band the Rolling Stones. A product of Mick Jagger and Keith Richards' songwriting partnership, it features a guitar riff by Richards that opens and drives the song. The riff is widely considered one of the greatest hooks in rock history. The song's lyrics refer to sexual frustration and commercialism.

The song was first released as a single in the United States in June 1965 and was also featured on the American version of the Rolling Stones' third studio album, Out of Our Heads, released that July. "Satisfaction" was a hit, giving the Stones their first number one in the US. In the UK, the song initially was played only on pirate radio stations, because its lyrics were considered too sexually suggestive. It later became the Rolling Stones' fourth number one in the United Kingdom.

It is one of the world's most popular songs, and was No. 31 on Rolling Stone magazine's "The 500 Greatest Songs of All Time" list in 2021. It was inducted into the Grammy Hall of Fame in 1998. The song was added to the National Recording Registry of the Library of Congress in 2006, the first and so far only Rolling Stones recording to be included in the Registry.

Keith Richards wrote "Satisfaction" in his sleep and recorded a rough version of the riff on a Philips cassette player. He had no idea he had written it. He said when he listened to the recording in the morning, there were about two minutes of acoustic guitar before you could hear him drop the pick and "then me snoring for the next forty minutes". Sources vary as to where this story happened. While they make reference to a hotel room at the Fort Harrison Hotel in Clearwater, Florida, a house in Chelsea, and the London Hilton, Richards wrote in his most recent autobiography that he was in his flat in Carlton Hill, St. John's Wood. He specifies that Mick Jagger wrote the lyrics by the pool in Clearwater, four days before they went into the studio, hence the confusion.

The Rolling Stones first recorded the track on 10 May 1965 at Chess Studios in Chicago, Illinois, which included Brian Jones on harmonica. The Stones lip-synched to a dub of this version the first time they debuted the song on the American music variety television programme Shindig! The group re-recorded it two days later at RCA Studios in Hollywood, California, with a different beat and the Maestro fuzzbox adding sustain to the sound of the guitar riff. Richards envisioned redoing the track later with a horn section playing the riff: "this was just a little sketch, because, to my mind, the fuzz tone was really there to denote what the horns would be doing." The other Rolling Stones (Jones, Watts, and Wyman), as well as producer and manager Andrew Loog Oldham and sound engineer David Hassinger eventually outvoted Richards and Jagger so the track was selected for release as a single. The song's success boosted sales of the Gibson fuzzbox so that the entire available stock sold out by the end of 1965.

Like most of the Stones' pre-1966 recordings, "Satisfaction" was originally released in mono only. In the mid-1980s, a true stereo version of the song was released on German and Japanese editions of the CD reissue of Hot Rocks 1964–1971. The stereo mix features a piano (played by session player Jack Nitzsche, who also provides the song's iconic tambourine) and acoustic guitar that are barely audible in the original mono release (both instruments are also audible on a bootleg recording of the instrumental track). This stereo mix of "Satisfaction" also appeared on a radio-promo CD of rare stereo tracks provided to US radio stations in the mid-1980s, but has not yet been featured on a worldwide commercial CD; even later pressings of the German and Japanese Hot Rocks CDs feature the mono mix, making the earlier releases with the stereo mix collector's items. For the worldwide 2002 reissue of Hot Rocks, an alternative quasi-stereo mix was used featuring the lead guitar, bass, drums, and vocals in the center channel and the acoustic guitar and piano "split" left and right via a delay effect.

The song opens with the guitar riff, which is joined by the bass halfway through. It is repeated three times with the drums and acoustic guitar before the vocal enters with the line: "I can't get no satisfaction." The key is E major, but with the 3rd and 7th degree occasionally lowered, creating – in the first part of the verses ("I can't get no ...") – a distinctive mellow sound. The accompanying chords (i.e. E major, D major and A major) are borrowed from the E mixolydian scale, which is often used in blues and rock.

The title line is an example of a negative concord. Jagger sings the verses in a tone hovering between cynical commentary and frustrated protest, and then leaps half singing and half yelling into the chorus, where the guitar riff reappears. The lyrics outline the singer's irritation and confusion with the increasing commercialism of the modern world, where the radio broadcasts "useless information" and a man on television tells him "how white my shirts can be – but he can't be a man 'cause he doesn't smoke the same cigarettes as me", a reference to the then ubiquitous Marlboro Cowboy style advertisement. Jagger also describes the stress of being a celebrity, and the tensions of touring. The reference in the verse to not getting any "girl reaction" was fairly controversial in its day, interpreted by some listeners (and radio programmers) as meaning a girl willing to have sex. Jagger commented that they "didn't understand the dirtiest line", as afterwards the girl asks him to return the following week as she is "on a losing streak", an apparent reference to menstruation. The song closes with a fairly subdued repetition of the song's title, followed suddenly by a full shout of the line, with the final words repeated into the fade-out.
