The American crocodile is a species of crocodilian found in the Neotropics. It is the most widespread of the four extant species of crocodiles from the Americas. Populations occur from the Atlantic and Pacific coasts of southern Mexico to South America as far as Peru and Venezuela.

The American is one of the larger crocodile species. Males can reach lengths of 6.1 m (20 ft), weighing up to 907 kg (2,000 lb). Despite their large size, American crocodiles do not regularly attack large animals, as most large crocodilians do. Fish, reptiles, birds and small mammals make up the majority of their diet. On occasion, large mammals such as deer and cattle are taken.
