Carlsbad Caverns National Park is a United States National Park in the Guadalupe Mountains in southeastern New Mexico. The primary attraction of the park is the show cave, Carlsbad Cavern. Visitors to the cave can hike in on their own via the natural entrance, or take the elevator directly to the Underground Lunchroom some 750 feet (230 m) below.

The park has two entries on the National Register of Historic Places: The Caverns Historic District and the Rattlesnake Springs Historic District. Approximately two thirds of the park has been set aside as a wilderness area, helping to ensure no future changes will be made to the habitat.

Peak visitation typically occurs on the weekends following Memorial Day and the Fourth of July. The park entrance is located on US Highway 62/180 approximately 18 miles (29 km) southwest of Carlsbad, New Mexico. The park participates in the Junior Ranger Program.

Carlsbad Cavern includes a large cave chamber, the Big Room, a natural limestone chamber which is almost 4,000 feet (1,220 m) long, 625 feet (191 m) wide, and 255 feet (78 m) high at the highest point. It is the third largest chamber in North America and the seventh largest in the world. The largest in the world is the Sarawak Chamber in Malaysia.
