The fourth season of Atypical will be its last. Set to air in 2021, the final season will consist of 10 half-hour episodes. "Our fans have been such beautiful, vibrant supporters of this show," showrunner Robia Rashid said in a statement about the show's final season. "Thank you for being so open to Sam's voice and stories, and those of the entire Gardner family. It's my hope that the legacy of Atypical is that more unheard voices continue to be heard and that even after this series ends."
