"You Could Be Mine" is a song by American rock band Guns N' Roses, featured on their 1991 fourth studio album Use Your Illusion II. It was released as the band's seventh single, and the first from the Use Your Illusion albums, in June 1991. Backed with "Civil War" from Use Your Illusion II, the single reached number 29 on the Billboard Hot 100 chart and number three on the UK Singles Chart.

The song was originally released as the theme song for director James Cameron's 1991 film, Terminator 2: Judgment Day.

Contrary to popular belief, "You Could Be Mine" was not originally going to be the official theme of Terminator 2: Judgment Day. However, the references to Guns N' Roses that were made in the film (from John Connor's friend's L.A. Guns T-shirt to the T-800 taking out his shotgun from a box of roses, thus playing a pun on the band's name) were so clear and obvious that it was a wise business decision to make when director James Cameron decided to recruit the band to perform a song. As it would turn out, "You Could Be Mine" was selected to be included in the film. Arnold Schwarzenegger had the band members over for dinner at his own home to negotiate the deal.

The lyric "With your bitch slap rappin' and your cocaine tongue you get nothin' done" from the chorus appeared on the inner sleeve of Guns N' Roses' debut album Appetite for Destruction, released in 1987 (the song had already been written by then). This "tradition" was followed by the line "Ain't It Fun" on the Use Your Illusion albums released in 1991 - two years later GN'R cover of the song "Ain't It Fun" appeared on "The Spaghetti Incident?" album. The end of first verse, "we've seen that movie too", is a reference to Elton John' song "I've Seen That Movie Too", from the album Goodbye Yellow Brick Road. Slash states that the song's writing began at the first preproduction session for Appetite for Destruction.
