"She's Out of My Life" is a song written by musical artist Tom Bahler. He wrote the song about Karen Carpenter, who broke up with Bahler after discovering he had fathered a child with another woman. The song has been covered by a variety of artists, including: Michael Jackson, Patti LaBelle, Ginuwine, 98 Degrees, Jon Lee, Barbara Mandrell, Willie Nelson, and Josh Groban.

The song became famous as the fourth single to be released by singer Michael Jackson from his successful Off the Wall album in 1979. It was the first time a solo artist had achieved four top ten hits from one album. Unlike the album's previous singles (which were all dance-oriented funk/disco songs), the "She's Out of My Life" song was an emotional ballad. Jackson's vocals on the record were considered by critics to be some of his best.
