Kamp Koral: SpongeBob's Under Years (also known as Kamp Koral) is an American animated television series that premiered on Paramount+ on March 4, 2021. The series is a prequel and spin-off of the Nickelodeon series SpongeBob SquarePants, which was created by Stephen Hillenburg. It features younger versions of the series' characters and follows them as they attend a summer camp. The series was developed by Luke Brookshier, Marc Ceccarelli, Andrew Goodman, Kaz, Mr. Lawrence, and Vincent Waller.

In October 2018, during his first days as president of Nickelodeon, Brian Robbins put a room together to brainstorm ideas for potential SpongeBob spin-off series'. In February 2019, it was reported that a SpongeBob spin-off series was in the works. In June 2019, the series was officially announced with a 13-episode first season, which was later expanded to 26 episodes in March 2021. The idea for Kamp Koral originated from the flashback scenes from the film The SpongeBob Movie: Sponge on the Run (2020).

In August 2021, the series was renewed for a second 13-episode season, which premiered on Paramount+ on July 10, 2024.
