Waiting for Guffman is a mockumentary starring, co-written and directed by Christopher Guest that was released in 1997. Its cast included Catherine O'Hara, Eugene Levy, Fred Willard, Parker Posey and others who would appear in several of the subsequent mockumentaries directed by Guest.

The title of the film is a reference to the Samuel Beckett play, Waiting for Godot — similarly, the titular character never appears. As in the other mockumentaries created by Guest, the majority of the dialogue is improvised. Because the film is about the production of a stage musical, it contains several original musical numbers.
