Is this the end of South Park? Hell no. The boys will be back in 2017 for South Park season 21.

The trolls didn’t start World War III after all. Get over it. That means South Park season 21 is still on track for 2017. For fans looking for some assurance after the season 20 finale, Comedy Central already has a contract in place to keep South Park on air through season 23.
The original contract was set to expire at the end of South Park season 20, but creators Matt Stone and Trey Parker renewed the contract in 2015.
At the time, Comedy Central put out a statement to celebrate the annoucement:
"South Park remains the bedrock of Comedy Central and we are thrilled that new episodes will continue to entertain audiences for years to come," said Michele Ganeless, president of Comedy Central, in a press release. "The series remains as urgent and relevant now as the day it premiered and at nearly 20 seasons in it continues to draw generations of new fans."
In the streaming sphere, South Park remains on Hulu, and will do so exclusively for the next four years. Limited free episodes are available on SouthPark.CC.com.
South Park Season 21 Release Date
South Park not longer splits its seasons between fall and spring. If the current pattern continues, we can expect South Park season 21 to premiere in September 2017. We’ll keep you posted on new information as we have it!
