Lemony Snicket's A Series of Unfortunate Events is a video game based on the Lemony Snicket book series and film, released by Activision in 2004 for the GameCube, PlayStation 2, Xbox, PC and Game Boy Advance platforms. A scaled-down version was developed and released by JAMDAT for Java Mobile Edition-compliant mobile phones.

The game is based primarily on the movie, which in turn is based on the plots of the first three books of the series: The Bad Beginning, The Reptile Room and The Wide Window. The game was released a few weeks before the movie's release, giving players a preview of what the movie would be like, albeit in video game format.

Players take the roles of Violet, Klaus, and Sunny Baudelaire, solving puzzles, fighting villains and finding objects. Players encounter characters such as Arthur Poe, Uncle Monty and Aunt Josephine, along with villains such as Count Olaf, The Hook-Handed Man, the White-Faced Women and The Bald Man with the Long Nose.
