Heathers: The Musical is a rock musical with music, lyrics and book by Laurence O'Keefe and Kevin Murphy, based on the 1988 film of the same name written by Daniel Waters. After a sold-out Los Angeles tryout, the show moved Off-Broadway in 2014. After the run in 2014 the show had an Off-West End run in 2018 and then transferred to the West End in 2018 for a limited engagement, this included the addition of some new songs.

While it is a high-energy black comedy, the show opens conversations about dark issues, including bullying, teen suicide, sexual assault, and violence in schools.
