Trinidad and Tobago dry forests are tropical dry forests located primarily in western and southern parts of the island of Trinidad, in southern parts of the island of Tobago and on smaller offshore islands including Chacachacare, Monos, Huevos, Gaspar Grande, Little Tobago and Saint Giles Island.

The major areas of dry forest in Trinidad include the Chaguaramas peninsula in the northwest, areas along the south coast of the island, from Cedros to Morne Diablo, and areas along the east coast including parts of the Guayaguayare, Mayaro and Manzanilla coastline.

In addition, areas along the west coast including San Fernando Hill and much of the former Sugar Belt also would have originally supported dry forest.

In Tobago much of the southwest of the island originally supported dry forests.

The dominant paradigm in phytosociology in Trinidad and Tobago has been the work of John Stanley Beard carried out in the 1940s.
