Tintorera is a 1977 Mexican-British horror film directed by René Cardona Jr. and starring Susan George, Hugo Stiglitz, Fiona Lewis and Andrés García. It is based on the novel of the same name by oceanographer Ramón Bravo, who studied the species of shark known as 'tintorera' (a 19-foot (5.8 m) shark) and discovered the sleeping sharks of Isla Mujeres. The film, along with many monster movies of the 1970s and 1980s, is very similar to Jaws. It is also known by the alternative title Tintorera: Killer Shark.

Quentin Tarantino paid tribute to this movie at the eighth Morelia International Film Festival, showing a copy from his private collection.
