Mortal Kombat: Rebirth is a 2010 American short fan film directed by Kevin Tancharoen, with fight choreography by Larnell Stovall. Based on the Mortal Kombat series of fighting games, the short-film "actually was made by the director to sell Warner Bros. Entertainment on his vision for a reimagined Mortal Kombat film." The pitch eventually evolved into the web series Mortal Kombat: Legacy.

The short-film features an alternative version of the Mortal Kombat universe. The characters of the game are portrayed with vastly different origins, based on realism. There is no mention of Outworld or any other supernatural elements, although the tournament itself is a main part of the storyline in this short. Tancharoen himself has noted that he wouldn't shy away from supernatural elements entirely, but they have to be "done in a very tasteful way".
