A Night at the Roxbury is a 1998 comedy film based on a recurring skit on television's long-running Saturday Night Live called The Roxbury Guys. Saturday Night Live regulars Will Ferrell, Chris Kattan, Molly Shannon, and Colin Quinn star.

The film sees Kattan and Ferrell reprise their SNL characters, dense nightclubbing brothers Doug and Steve Butabi. In the original sketches, Doug and Steve were often joined by that night's guest, credited as 'barhop' (including turns by Jim Carrey, Tom Hanks, Martin Short, Alec Baldwin, Jack Nicholson, and Sylvester Stallone parodying his familiar Rocky Balboa role), but the barhop role was dropped during production of the film.
