Super Mario Bros. (also known as Super Mario Bros.: The Movie) is a 1993 fantasy adventure comedy film based on Nintendo's Super Mario video game series. The first American feature-length live-action film based on a video game, it was directed by the husband-and-wife team of Rocky Morton and Annabel Jankel, written by Parker Bennett, Terry Runté, and Ed Solomon, and distributed by Buena Vista Pictures through Hollywood Pictures. It follows brothers Mario (Bob Hoskins) and Luigi Mario (John Leguizamo) in their quest to rescue Princess Daisy (Samantha Mathis) from a dystopic parallel universe ruled by the ruthless President Koopa (Dennis Hopper).

Development began after producer Roland Joffé obtained the Mario film rights from Nintendo. Given free creative license by Nintendo, which believed the Mario brand was strong enough for experimentation, the screenwriters envisioned Super Mario Bros. as a subversive comedy influenced by Ghostbusters (1984) and The Wizard of Oz (1939). The setting was inspired by the game Super Mario World (1990) with elements drawn from fairy tales and contemporary American culture. The production innovated and introduced many filmmaking techniques considered pivotal in the transition from practical to digital visual effects, including the use of Autodesk Flame. Filming took place from May to July 1992.

Released on May 28, 1993, Super Mario Bros. was a critical and financial failure, grossing $38.9 million worldwide against a budget of $42–48 million. Although the film received generally unfavourable reviews at release and appeared on several lists of the worst films ever made, it has developed a cult following over the years. In 2013, a webcomic sequel was produced in collaboration with Bennett.

After Super Mario Bros., Nintendo would not license another film based on the Super Mario game series until the 2023 animated film titled The Super Mario Bros. Movie.
