Carlsbad Caverns National Park is a national park of the United States in the Guadalupe Mountains of southeastern New Mexico. The primary attraction of the park is the show cave Carlsbad Cavern. Visitors can hike in on their own via the natural entrance or take an elevator from the visitor center.

The park entrance is located on US Highway 62/180, approximately 18 miles (29 km) southwest of Carlsbad, New Mexico. 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 that no future changes will be made to the habitat.

Carlsbad Cavern includes a large limestone chamber, named simply the Big Room, which is almost 4,000 ft (1,220 m) long, 625 ft (191 m) wide, and 255 ft (78 m) high at its highest point. The Big Room is the largest chamber in North America and the 32nd largest in the world.

Carlsbad Caverns was established as a national park in 1930 and was recognized as a World Heritage Site in 1995. According to The Travel, it is renowned globally for being "one of the most accessible and best-preserved cave complexes in the world".
