South Park Rally is a kart-style racing video game based on the American animated comedy series South Park. The game is developed by Tantalus Interactive and was the last to be published by Acclaim Entertainment (with currently distributed by Comedy Central and CollectorVision Games) near the end of the third season of the show for the PlayStation in 1999, which was later ported to Microsoft Windows in 1999 for North America and in 2000 for Europe and for Nintendo 64 and Dreamcast in 2000, the game includes many characters, vehicles, locations, items and other features inspired by or featured on the series.

Development on the title – based on Tantalus' own concept – was done on three platforms simultaneously, and took seven months. South Park Rally was the third video game based on the series, as Acclaim had also published the games South Park (1998) and South Park: Chef's Luv Shack (1999).

South Park creators Trey Parker and Matt Stone had little to do with the development of South Park Rally (as well as the two other Acclaim releases), although they did contribute a number of original lines of voice acting for it, as they do most of the voices on the show. Over time, Parker and Stone have publicly criticized Acclaim and the quality of the games as well.
