Survivor: Cambodia

Survivor: Cambodia — Second Chance is the 31st season of the American CBS competitive reality television series Survivor. Unlike previous seasons, which were completely cast by producers, this season featured 20 returning contestants chosen by an online public vote. The ballot, with the 32 finalists that were considered for this season, was revealed on May 6, 2015, the same day that voting began. The final cast was revealed on May 20, at the reunion of the preceding season. After the reveal occurred, the chosen cast members immediately began the trip to Koh Rong, Cambodia, where the season was filmed.

It is the tenth season to feature returning players, and the third to feature a cast consisting entirely of returning players, after Survivor: All-Stars and Survivor: Heroes vs. Villains. Though this season was the 31st to air, it was the 32nd to film, after the subsequently-aired Survivor: Kaôh Rōng; the two seasons were filmed back-to-back in the same location. This season featured several new alterations to the game format. Hidden immunity idols, typically hidden either at tribal camps or Exile Island, were hidden this season at immunity challenges before the merge. Additionally, this season marked the first time the number of regular tribes increased over the course of a season (in this case, from two to three), and the first time the tribes merged with 13 players remaining. It also introduced the vote stealer, in which one player could prohibit another from voting and cast a second ballot in their stead.

A DVD release of the season was released by Amazon.com on November 13, 2018.

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

This season was preceded by Survivor: Worlds Apart and followed by Survivor: Kaôh Rōng.
