Mortal Kombat: Legacy is an American web series anthology adapted from the fictional universe of the Mortal Kombat video game franchise. It debuted on Machinima.com's YouTube channel on April 11, 2011.

The show's premise originated with director Kevin Tancharoen's short film titled Mortal Kombat: Rebirth, which portrayed the background to the original game's story in a realistic way. Seeking the green-light from the studio for production on a re-imagined Mortal Kombat film, he submitted the concept to Warner Bros., which declined to back the film, despite the attention and positive fan reception. Instead Tancharoen got the go-ahead to shoot the web series.

The first season of Mortal Kombat: Legacy is a prequel to the original game, explaining the background stories of several characters from the series and demonstrating their reasons for participating in the upcoming tenth Mortal Kombat tournament, on which the first game was based. The episodes are non-linear with minimal continuity and each devoted to the story of a specific character or characters. The second season covers the tournament itself.
