As of 2025, South Park is available for streaming on Paramount+. This includes all seasons from the very first to the latest. New episodes of South Park air on Comedy Central and are made available for streaming on Paramount+ the day after their broadcast. Previously, South Park was on HBO Max, but as of August 2025, it has been removed from that platform. Paramount+ is now the exclusive streaming home for the series in the U.S., following a major $1.5 billion agreement for the global streaming rights. In addition to Paramount+, you can watch new episodes live on Comedy Central or through live TV streaming services that carry Comedy Central, such as Philo, DirecTV, FuboTV, and Sling TV, with Paramount+ being the main on-demand streaming service for the show.
So, the primary streaming service to watch South Park now is Paramount+.
