Friday the 13th: A New Beginning (also known as Friday the 13th Part V: A New Beginning) is a 1985 American slasher film directed by Danny Steinmann and starring Melanie Kinnaman, John Shepherd, and Shavar Ross. The film also features a cameo appearance from Corey Feldman, who portrayed Tommy Jarvis in the previous film. It is a sequel to Friday the 13th: The Final Chapter (1984) and the fifth installment in the Friday the 13th franchise. Set years after the events of the previous film, the story follows a teenage Tommy Jarvis (Shepherd), who is institutionalized at a halfway house near Crystal Lake because of nightmares of mass murderer Jason Voorhees, whom he killed as a child. Tommy must face his fears when a new hockey mask-wearing murderer initiates another violent killing spree in the area.

A New Beginning features a high number of on-screen murders. Aside from its gore and violence, the film has also become known for its explicit nudity, sex scenes, and numerous depictions of illicit drug use. Peter Bracke's book Crystal Lake Memories: The Complete History of Friday the 13th details that behind the scenes, the production was plagued with hardcore drug use.

Shot in California in 1984 on a budget of $2.2 million, A New Beginning was released theatrically on March 22, 1985, and grossed $21.9 million at the U.S. box office. The film was initially going to set up a new trilogy of films with a different villain for the series but, after a disappointing reception from fans and a steep decline in box-office receipts from Friday the 13th Part III (1982) and The Final Chapter, Jason Voorhees was brought back for the next installment Friday the 13th Part VI: Jason Lives (1986) and has been the main antagonist in the series since. In addition to weak box office returns, the film received mostly negative reviews from critics.
