"Survivor: Cook Islands" is the thirteenth season of the reality television series Survivor, which premiered on September 14, 2006.

The show was filmed in the Cook Islands and featured 20 contestants competing for a million-dollar prize. The season concluded with Yul Kwon emerging as the winner, receiving the title of Sole Survivor. The season was praised for its strategic gameplay and diverse cast, but it also sparked discussions about race and representation in reality television.
