An Awfully Big Adventure is a 1995 British coming-of-age film directed by Mike Newell. The story concerns a girl who joins a local repertory theatre troupe in Liverpool. During a winter production of Peter Pan, the play quickly turns into a dark metaphor for youth as she becomes drawn into a web of sexual politics and intrigue.

The title is an ironic nod to the original Peter Pan story, in which Peter says, "To die will be an awfully big adventure." Set in 1947, the film was adapted from the Booker Prize-nominated 1989 novel of the same name by Beryl Bainbridge.
