Ghost Shark is a 2013 American supernatural monster film directed for the Syfy television network by Griff Furst. With Furst joined by Paul A. Birkett and Eric Forsberg for screenwriting, the film premiered on Syfy on August 22, 2013.

Despite being panned critically, the film attracted attention on social media due to its fantastical premise. Websites such as Vulture commented on moments from the film. An unofficial sequel, Ghost Shark 2: Urban Jaws, was released on 1 July 2015. The two films are unrelated in terms of narrative, other than both being films featuring killer sharks.
