Start with season 1, which opened on Comedy Central on 13 August 1997. Seasons 1 through 28 are complete. Season 29 began on 16 September 2026; only South American Biker Gangs is listed, because the later 2026 episodes have not aired. The theatrical film South Park: Bigger, Longer & Uncut (30 June 1999) sits beside the series, not inside a season. The Paramount+ specials are not episodes of those seasons.
