Outlast is an American survival reality competition television series that takes place in Alaska. All eight episodes of the first season premiered on March 10, 2023, on Netflix. It is produced by Aggregate Films and Nomad Entertainment, with Mike Odair serving as the showrunner, and Jason Bateman, Grant Kahler, Michael Costigan, Emma Ho, and Odair serving as executive producers. In May 2023, the series was renewed for a second season.

The series places 16 players, initially split into four teams, in the Alaskan wilderness, where they must survive off the land with meager supplies. In season one, the players were described as "lone wolf" survivalists, who were challenged to work in teams and not allowed to compete alone. Season two included a variety of occupations and personalities. Players can only leave the game by firing a flare gun, which is automatically triggered by emergency rescue or medical evacuation. The last remaining team of two or more people wins one million dollars. After a specific number of days have passed with only two teams, a navigation and endurance race is initiated to obtain the prize money.
