"Fallen Angel" is the second single from Open Up and Say...Ahh!, American glam metal band Poison's second studio album. The b-side of the seven inch was "Bad to Be Good".

Released as a single in 1988 on Capitol Records, the track reached #12 on the Billboard Hot 100 and #32 on the Mainstream rock charts and has since gone Gold in the US. This made it the only single from the album not to reach the Top Ten. It also charted at number 21 on the Australian charts and number 59 on the UK Singles chart.

The song is about a young girl who grew up in a small town and goes to Los Angeles to try to make it as an actress. While there, she abandons her old life...

This theme is a reference to the history of the band Poison itself: Bret Michaels, Bobby Dall and Rikki Rockett all left their native Pennsylvania for Los Angeles in their quest for fame.

"Fallen Angel", along with "Talk Dirty to Me," "I Won't Forget You" and "Ride the Wind," was the subject of a lawsuit in 2011 by members of the defunct band Kid Rocker, who claimed that the songs were based on Kid Rocker songs played to Poison guitarist C.C. DeVille before he was a member of Poison. On April 8, 2013, a California federal judge said that the plaintiffs waited too long to file their lawsuit, stating, "It is totally implausible that plaintiff did not discover the alleged infringement until 2011." The judge ruled that the plaintiffs could only sue for damages dating back three years from the date of the lawsuit (following a three-year statute of limitations), and no more.
