American McGee Presents: Bad Day L.A., also known as simply Bad Day L.A., is a 2006 third-person action video game by American McGee. Players assume the role of Anthony Willams, a former Hollywood agent turned homeless man in Los Angeles. During this time LA is ravaged by both natural and man-made disasters. Anthony only wishes to save himself, though through the course of the story he becomes an unwilling savior. The game's attempted tone is one of political satire, targeting all spectra of politics.

While the game was set for world release on September 6, 2006, it first saw the light of day as part of the 9/2006 issue (released at the end of August 2006) of the Polish video game magazine CD-Action.

The game was released to mostly negative reviews, with reviewers criticizing its gameplay, visuals, voice acting, characters, offensive and crass humor, and poor attempts at satire.
