The Montes de María is an isolated group of small mountains near the northern coast of Colombia in the Caribbean Region.

Montes de María is a zone located in the center of the Colombian Departments of Bolívar and Sucre.

The following towns are part of the Montes de María: El Carmen de Bolívar, María La Baja, San Juan Nepomuceno, San Jacinto, Córdoba, Zambrano and El Guamo in Bolívar; Ovejas, Chalán, Colosó, Morroa, Toluviejo, Los Palmitos and San Onofre in Sucre.

Montes de María comprises two zones: The first zone called Baja Montaña is relatively flat with no mountains: the area located between the Troncal de Occidente and the Magdalena River is dedicated to cattle-raising and forestry, while the area located between the Transversal del Caribe and the Canal del Dique is mainly agricultural.

A second, called Alta Montaña, zone located between the Transversal del Caribe and Troncal de Occidente also has agriculture as the main activity.
