National Museum of the American Indian, Smithsonian Institution museum established by an act of Congress in 1989, with branches in New York City; Suitland, Maryland; and Washington, D.C. Permanent and temporary exhibits showcase the diverse heritage and history of North and South American Indians. With more than 800,000 cultural artifacts on display and a collection of 90,000 photographs, the museum is the largest of its kind in the world. Through its program of lectures, seminars, performances, storytelling, film, and multimedia resources, the museum educates visitors in the cultural practices and identities of hundreds of indigenous tribes. All three facilities were designed in consultation with Native American peoples.

The museum had its origins in the collections of George Gustav Heye (1874–1957), who established his Museum of the American Indian, Heye Foundation, in 1916. His collection became part of the Smithsonian in 1990, and in 1994 the George Gustav Heye Center of the National Museum of the American Indian was opened in the historic Alexander Hamilton U.S. Custom House on Bowling Green in Manhattan. The Heye Center features a collection of films by and about Native Americans and frequently hosts public education programs such as dance and music performances.

The Cultural Resources Center in Suitland opened to the public in 1998. This facility houses, preserves, and organizes the museum’s extensive exhibits and research. Much of the behind-the-scenes curatorial and managerial work is completed there, with a focus on Native approaches to care and use of the exhibits.

In 1994 Washington, D.C., became home to the museum’s third and largest facility. The museum was designed by Blackfoot architect Douglas Cardinal in conjunction with other Native advisers and houses three permanent exhibits—seasonal festivals and cosmological perspectives, history of the American Indians, and contemporary Native peoples—as well as several temporary exhibits.
