Cocaine Shark is a 2023 English-language Japanese horror film directed by Mark Polonia.

[1] The film features various mutated creatures, none of which are actually sharks on cocaine as the title suggests.

[1][3] When asked about the possibility of the film, Elizabeth Banks, the director of Cocaine Bear, expressed interest in directing it.

The film debuted on January 29, 2023, in Japan under the title Kanizame Shakurabu, or Crab Shark.

It has been described as "terrible and lazy", with criticism aimed at the plot, camerawork, acting, lighting, and special effects.
