The Red River Gorge is a canyon system on the Red River in east-central Kentucky. Geologically, it is part of the Pottsville Escarpment.

Much of the Gorge has been purchased as part of the Daniel Boone National Forest and has been subsequently reserved as the Red River Gorge Geological Area, an area of around 28,000 acres (over 113 km²). It has been designated a National Natural Landmark.

This intricate canyon system features an abundance of high sandstone cliffs, rock shelters, waterfalls, and natural bridges. There are almost four dozen natural bridges known in this area.

Kentucky's Natural Bridge State Park is immediately adjacent to this area, featuring one of the largest natural bridges.

Because of its unusual and rugged nature, the Red River Gorge features a remarkable variety of ecological zones. It is the farthest southern site where the Canadian yew, Taxus canadensis, is known to grow.
