Cronos is a 1992 Mexican independent horror drama film written and directed by Guillermo del Toro and starring Federico Luppi and Ron Perlman. Cronos is del Toro's first feature film, and the first of several films on which he worked with Luppi and Perlman.

Critical reviews were overwhelmingly positive, praising the inventive direction and creative storytelling, and over time Cronos has been regarded as a classic. The film was selected as the Mexican entry for the Best Foreign Language Film at the 66th Academy Awards, but was not accepted as a nominee.

A stand-alone sequel, We Are What We Are, was released in 2010. The only connection being Daniel Giménez Cacho reprising his role as Tito the Coroner.
