Bob Roberts is a 1992 film written and directed by Tim Robbins. It is a satirical mockumentary, chronicling the rise of Bob Roberts, a conservative politician who is a candidate for an upcoming United States Senate election. Roberts is well financed, due mainly to past business dealings, and is well known for his music, which presents conservative ideas as rebellious. The film suggests that shady deals, hypocrisy and deceit are mainstays of US politics.

The film is based on a short segment, also named Bob Roberts and featuring the same character, that Robbins did for the television sketch comedy program Saturday Night Live on December 13, 1986, and is Robbins's directorial debut.
