"Opposites Attract" is a song recorded by Paula Abdul, featured on her debut album Forever Your Girl. It was written and produced by Oliver Leiber, who came up with the title after browsing a bookstore. Vocals on the song, in addition to Abdul, were provided by Bruce DeShazer and Marv Gunn, aka 'The Wild Pair'. "Opposites Attract" was the sixth and final single from the album, and achieved success in many countries, including the US and Australia where it was a #1 hit.

The lyrics are about a couple who love each other despite being different in just about every way possible.

The song is distinctive for its colorful music video created and directed by Candace Reckinger & Michael Patterson, in which Paula dances with cartoon character MC Skat Kat, voiced by 'The Wild Pair'. The music video adds an intro rap performed by Romany Malco. An additional rap was provided by Derrick 'Delite' Stevens for the Street mix version of the song, which was edited for the 7"/video.

The idea of MC Skat Kat came from the Gene Kelly movie Anchors Aweigh, where Kelly dances with Jerry, the mouse from the Tom and Jerrycartoon series. Paula even choreographed the animated character's moves to match her live-action dance moves in the video. MC Skat Kat was animated by members of the Disney animation team, working outside the studio between major projects, under the direction of Chris Bailey. Also shown in the video are Micetro, Taboo, and Fatz, yet their names weren't revealed until the release of The Adventures of MC Skat Kat and the Stray Mob.

The video won Abdul a Grammy award in 1991 for "Best Short Form Music Video".

The song was covered by American indie band Mirror Ball Associates for the album Covers Vol. 1, which features Paul Durham (lead singer of Black Lab) on vocals.

This video was later parodied by the Family Guyepisode "The Father, the Son, and the Holy Fonz" with Peter Griffin "dressed like a cat", taking the place of MC Skat Kat. Paula herself actually appears in the sequence. According to the DVD commentary, Abdul rerecorded her vocals specifically for the episode.

The song was also featured in hit comedy TV show Sabrina, The Teenage Witchin the Season 4 episode "Aging, Not So Gracefully".

The Australian sketch comedy show Fast Forwardparody of the song had Humphrey B. Bear in place of MC Skat Kat.

The song also appeared in the television version of the political thriller A Very British Coup.
