"Look Away" is a 1988 power ballad by American rock band Chicago. Written by Diane Warren, produced by Ron Nevison, and with Bill Champlin on lead vocals, it is the second single from the band's album Chicago 19. Look Away is Chicago's biggest selling single of all time, it topped the Billboard Hot 100 for two weeks in December 1988, matching the chart success of the group's "If You Leave Me Now" (1976) and "Hard to Say I'm Sorry" (1982). "Look Away" is Chicago's seventh song to have peaked at number one on the Adult Contemporary chart as well as the number one song on the 1989 year-end Billboard Hot 100 chart, even though it never held the #1 spot at all in 1989.

The song, unlike hits from early in Chicago's career, does not prominently feature horns. It is also the band's first number-one single following the departure of Peter Cetera, who left the group in 1985.

According to drummer Danny Seraphine, Chicago's manager Howard Kaufman suggested that the band bring in outside songwriting help. Kaufman recommended Diane Warren, who also composed the band's single "I Don't Wanna Live Without Your Love," and producer Ron Nevison, who had worked with Heart on the number one hits "These Dreams" and "Alone."

Warren wrote "Look Away" from the man's perspective and submitted a demo to Chicago's management company. "Diane's demos always sound really good," Nevison said. "Her demos are always very simple, but they always have great vocal performances." Bassist Jason Scheff remarked, "The songs that last for me are the ones I don't get at first," and added, "I remember hearing 'Look Away' and thinking it's okay, but not great. Thank God I'm not an A&R man."
