Mountain Pine Ridge Forest Reserve is a protected area in the Cayo District of southern central Belize.

The Maya had a city at Caracol on the borders of the modern reserve as early as 1200 BC, and Mayan artifacts discovered in Barton Creek Cave suggest that it was used as a ritual site.

The reserve is home to various large mammals, including cougars, jaguars, ocelots, white-nosed coatis, and Baird's tapirs.

Native species of bird include the rufous-capped warbler, common crossbill, pine siskin, eastern bluebird, stygian owl, king vulture, ocellated turkey, acorn woodpecker, Lesson's motmot, plumbeous vireo, keel-billed toucan and red-lored parrot.

It is accessible only by boat, and archaeological investigations have uncovered a large number of Mayan relics from the various ledges above the river, suggesting it was used for rituals.

Baldy Beacon provides uninterrupted views over the reserve, as its soil is too poor to support any vegetation other than some hardy grasses.

The area is sparsely populated with the highest concentration (a few hundred people) located at Douglas D' Silva Forest Station, the administrative headquarters of the Western Division of the Forestry Department.
