"We Love You" is a rock song written by Mick Jagger and Keith Richards, first released as a single in the UK by The Rolling Stones on 18 August 1967, with "Dandelion" as the B-side. It reached the top ten in Britain, peaking at No. 8, but only made it to No. 50 in the US, where "Dandelion" (which reached No. 14) was promoted as the A-side. The song features uncredited backing vocals by John Lennon and Paul McCartney.

This single's two tracks would be the final Stones recordings receiving a production credit for band manager Andrew Loog Oldham.

Allen Ginsberg was in London for a pro-marijuana rally in Hyde Park. He met Jagger at McCartney's house, and Jagger invited the Beat poet to that night's session with McCartney and Lennon to record uncredited backing vocals for "We Love You". Ginsberg, waving his Shiva beads and a Tibetan oracle ring, conducted the singers from the other side of the studio glass to the tempo of the stuttering Mellotron track. "They looked like little angels," he wrote later of the Stones and Beatles, "like Botticelli Graces singing together for the first time."

Written in the aftermath of the drugs arrests faced by Jagger and Keith Richards at the Redlands country home of the latter in Sussex that year, the single opens with the sounds of entry into jail, and a cell door clanging shut. The draconian nature of the sentences handed down to the two Stones relative to the charges prompted a stern editorial by The Times in protest. The song's lyric, seemingly "a spoof" or echo of the Beatles' "All You Need Is Love" (which Lennon, in his famous 1970 Rolling Stone interview, insisted it was) broadcast from earlier in the summer, on closer examination espouses a strong anti-establishment posture, proclaiming "we don't care if you hound we and lock the doors around we" and "you will never win we, your uniforms don't fit we."
