South Park season 27 airs new episodes on Wednesdays at 10 PM Eastern/Pacific on Comedy Central in the US. The season began on July 23, 2025. The episodes are currently released every two weeks rather than weekly. Paramount+ subscribers can stream the new episodes the day after they air on Comedy Central. For example, episode 3 aired on August 20, 2025. Upcoming episodes are scheduled for dates including September 3 and September 17, 2025. The season consists of 10 episodes in total, and the schedule has been somewhat irregular with breaks and delays.
In the UK, episodes air every other Thursday at 10 PM on Comedy Central UK, a day after US broadcasts.
So currently, to watch South Park, look for new episodes on Wednesdays at 10 PM Eastern/Pacific on Comedy Central, with availability on Paramount+ the next day.
