Navajo Nation Museum, Cultural museum in Window Rock, Arizona, United States.

The Navajo Nation Museum is a museum in Window Rock, the capital of the Navajo Nation, that holds collections of art, photographs, artifacts, and archival materials related to Navajo history and culture. Its exhibition spaces are open to the public and display these materials in organized galleries.

A Navajo Tribal Museum opened in 1961 in a small building on the Window Rock Tribal Fairgrounds. In 1982 it moved into the back room of an arts and crafts store. The current building, officially the Navajo Nation Museum, Library & Visitor's Center, was constructed in 1997 at a cost of $7 million.

The exhibitions show weavings, jewelry, and traditional objects made by Navajo artists across different generations. Walking through the rooms, visitors can see how craft traditions have continued to the present day.

The museum sits in Window Rock and is best reached by car, as public transport options in the area are limited. It is worth checking ahead of the visit which spaces are open to the public, since some areas may occasionally be set aside for research purposes.

The museum has worked with film studios to produce dubbed versions of popular movies in the Navajo language. This effort supports the transmission of the language to younger generations in an accessible and familiar format.
