"I'm Already Taken" is the debut single by American country music artist Steve Wariner, released in April 1978. It peaked at number 63 on the U.S. Billboard country singles chart. In 1999, Wariner re-recorded the song for his album Two Teardrops. He released this re-recording in July as that album's second single, taking to number 3 on the same chart, as well as number 42 on the Billboard Hot 100.
Wariner co-wrote the song when he was 23 years old. The rendition from Two Teardrops includes a backing vocal from his brother, Terry, who has also sung backing vocals in Wariner's road band. Conway Twitty recorded the song on his 1981 album Mr. T. Conway's daughter Kathy Twitty provided the female backing vocals on his version.
