"Deliver" is a song recorded by American girl group Fifth Harmony from their self-titled third studio album (2017). It was released on August 25, 2017 as a promotional single. The Stereotypes produced "Deliver" and wrote it with Taylor Parks, and Whitney Phillips. An R&B, pop, and soul song, it includes lyrics about sexuality. Fifth Harmony based the song on 1990s R&B music by artists including Mariah Carey and Destiny's Child. Some critics praised "Deliver" for its composition and the group's vocals, while others were uncertain about its relevancy to 2017 music.
