Arches National Park is a United States national park located in the northern Colorado Plateau on the Colorado River north of the town of Moab in the U.S. state of Utah. It preserves the world's largest concentration of natural arches, which are constantly being created and destroyed by erosion and weathering. There are over 2000 arches in the park area with an opening of at least 90 cm (3 feet). The ecosystems of the park, which covers more than 300 km², range from the banks of the Colorado River to bare rock and are characterized by the average altitude of about 1500 m above sea level in a desert climate.

The area was designated a National Monument in 1929 and upgraded to a National Park in 1971. It is maintained by the National Park Service.
