Little Bighorn Battlefield National Monument preserves the site of the June 25 and 26, 1876, Battle of the Little Bighorn, near Crow Agency, Montana, in the United States. It also serves as a memorial to those who fought in the battle: George Armstrong Custer's 7th Cavalry and a combined Lakota-Northern Cheyenne and Arapaho force. Custer National Cemetery, on the battlefield, is part of the national monument. The site of the connected military action led by Marcus Reno and Frederick Benteen is also part of the National Monument, but is about 3 miles (4.83 km) southeast of the main site.

As part of a series of censorship actions at several National Park Service sites, in February 2026 the Trump Administration removed signage that described the background of the Battle of Little Bighorn and Native American boarding schools. Changes were opposed by the Northern Cheyenne Tribal Council.
