Survivor: Winners at War

Survivor: Winners at War is the 40th season of the American competitive reality television series Survivor. This season, filmed in May and June 2019, is the eighth consecutive season to be filmed in Fiji. Celebrating the show's twentieth anniversary milestone, the season featured twenty returning winners from past Survivor seasons competing for a $2 million prize. Due to the COVID-19 pandemic, the usual live finale for the winner reveal was replaced by a live teleconference between host Jeff Probst, situated in his garage, and the finalists in their respective homes.

This season is the thirteenth season to feature returning players, and the fifth season to feature only returning players. In addition, the season brought back the Edge of Extinction twist first introduced in the show's thirty-eighth season, where voted-out players could opt to stay for a chance to return into the game. The season introduced fire tokens, a form of currency that could be used by remaining players in the game to buy rewards or advantages. This was also the last season to be played over 39 days.

The season was preceded by a retrospective special titled Survivor at 40: Greatest Moments and Players on February 5, 2020, which featured interviews with past players, series highlights and first few minutes of the premiere episode.

The winner of this season was TBA, who defeated TBA and TBA by a vote of TBA.

This season was preceded by Survivor: Island of the Idols and followed by Survivor 41.
