The twelfth season of South Park, an American animated television series created by Trey Parker and Matt Stone, began airing on March 12, 2008.

Saturday Night Live cast member Bill Hader is credited as a consultant starting with this season.

Parker and Stone said they had considered intentionally redubbing the episode poorly if John McCain had won.

[1] The twelfth season of South Park has been met with mostly positive reviews from critics and fans.

That's a rarity for a series that often has fans calling up friends the next morning to say "Oh my God, did you see South Park?".

South Park: The Complete Twelfth Season was released as a three-disc Region 1 DVD box set in the USA on March 10, 2009, nearly one year after it had begun broadcast on television.
