Deborah Ann Gibson (born August 31, 1970) is an American singer-songwriter, record producer, and actress.

Gibson released her debut album Out of the Blue in 1987, which spawned several international hits, later being certified triple platinum by the Recording Industry Association of America. One of those singles, "Foolish Beat", made Gibson the youngest female artist to write, produce, and perform a Billboard Hot 100 number-one single. Her double-platinum second album Electric Youth (1989), gave Gibson another U.S. number-one hit with "Lost in Your Eyes". Gibson is the sole songwriter on all of her singles to reach the top 20 of the Billboard Hot 100. She was recognized by ASCAP as Songwriter of the Year, along with Bruce Springsteen, in 1989.

Gibson continued to record and release music throughout the 1990s and 2000s. In 2006, she reached number 24 on the U.S. adult contemporary chart with "Say Goodbye", a duet with Jordan Knight, and in 2017 achieved her highest-charting hit in more than 25 years in her duet with Sir Ivan, "I Am Peaceman". Gibson's 2020 single "Girls Night Out" became her first top five and highest-charting hit after 30 years. In addition to music, she has gone on to starring roles on Broadway and touring musicals, including playing Eponine in Les Misérables and Sandy in Grease, as well as television and independent film work.
