The thirteenth season of the American animated television series SpongeBob SquarePants, created by former marine biologist and animator Stephen Hillenburg, began airing on Nickelodeon in the United States on October 22, 2020, and ended on November 1, 2023. It consists of 26 episodes comprising 52 segments, alongside two standalone clip show specials, making it the longest season to date episode-wise. The series chronicles the exploits and adventures of the title character and his various friends in the fictional underwater city of Bikini Bottom. This is the first season without Hillenburg's involvement, following his death on November 26, 2018, though he is still credited as an executive producer. During this season, showrunners and co-executive producers Marc Ceccarelli and Vincent Waller were promoted to executive producer roles.
