Mountain Pine Ridge Forest Reserve is a nature reserve in the Cayo District of southern central Belize. It was established in 1944 to protect and manage the native Belizean pine forests. Its boundaries are poorly defined, but it is estimated to cover an area of 106,352.5 acres (430 km2), although much of the reserve has been leased.

Belize is a country on the north-eastern coast of Central America. It is bordered by Mexico to the north, the Caribbean Sea to the east, and Guatemala to the west and south. It also shares a water boundary with Honduras to the southeast.
