The McCurtain County Wilderness Area is a 14,087 acres (5,701 ha) wilderness nature preserve 25 miles (40 km) north of Broken Bow, Oklahoma.

[1] It was designated a National Natural Landmark in December 1974 for its excellent example of a xeric upland oak-pine forest.

It receives 47.5 inches (121 cm) of rain annually, the highest amount in the state.

There are over 110 bird species in the area, including the endangered red-cockaded woodpecker[3] and bald eagle.
