Tommy Boy is a 1995 American road comedy film directed by Peter Segal, written by Bonnie and Terry Turner, produced by Lorne Michaels, and starring former Saturday Night Live castmates and close friends Chris Farley and David Spade. This was the first of many movies that Peter Segal has filmed with former SNL castmates. The film was shot primarily in Toronto and Los Angeles under the working title "Rocky Road". It tells the story of a socially and emotionally immature man (Farley) who learns lessons about friendship and self-worth following the sudden death of his industrialist father. The film did well commercially, but received mixed reviews from critics. However, since its release, Tommy Boy has become a cult classic due to being very successful on home video.

The film, along with 1994 horror film Wes Craven's New Nightmare, is dedicated to Gregg Fonseca (1952 - 1994), who died eight months before its release.
