"I Ain't Gonna Eat Out My Heart Anymore" is a song written by Pam Sawyer and Laurie Burton, originally recorded by The Young Rascals. It was released as their first single in November 1965 and featured on their eponymous debut album the following year. A minor hit when released, the song peaked at number fifty-two on the US Billboard Hot 100 singles chart.

In 1966 the British band The Primitives covered the song in Italian. The song was called "Yeeeeeeh!" and became a hit. It was also covered by the Canadian garage band The Ugly Ducklings on their debut (and only) album Somewhere Outside issued in 1966.

The song was covered by glam rock band Angel in 1978 for their album White Hot. It was the band's only Top 50 hit, reaching #44 on the Billboard Hot 100 that year.

The Jackson 5 recorded the song in 1971 during the sessions for their album, Maybe Tomorrow, however it remained unreleased until its inclusion on their 1979 album, Boogie.

Southside Johnny and the Asbury Jukes covered this on 1983's Trash it Up.

The song is sung by Deborah Harry in the 1992 movie Intimate Stranger.

Shania Twain covered the song in 1990; the recording, however, was not released until 2001 on her album The Complete Limelight Sessions.

In late 1992, Australian rock duo Divinyls covered the song for the soundtrack to the film Buffy the Vampire Slayer. It was also issued as the lead single from their second compilation album, The Collection. The single went to the top twenty in Australia (peaking at number nineteen), and spent sixteen weeks in the top fifty.
