Antelope Valley Indian Museum State Historic Park, Ethnographic museum and California state historic park in Lancaster, United States.

The Antelope Valley Indian Museum is a chalet-style building of pale stucco over dark timber, with a steep shingled roof and a triangular gable, raised over the rock formation of Piute Butte in the Mojave Desert. A stone retaining wall at its base holds a wooden wagon wheel and an animal skull near the entry. Inside, the combined collections of H. Arden Edwards and Grace Oliver interpret Native American cultures of the Southwest, Great Basin and California.

Homesteader and artist H. Arden Edwards built the chalet-style house in 1928 over the rock formation of Piute Butte. Anthropology student Grace Oliver, a later owner, added her collection to his. The building is listed on the National Register of Historic Places and became a California state historic park in 1979.

The museum's name comes from its setting on Piute Butte in the Antelope Valley, and its exhibits interpret Native American groups of the Southwest, Great Basin and California. Many pieces are rare or one-of-a-kind. Each fall an opening event includes a traditional ground blessing ceremony, with Native American artists demonstrating and selling their work, food, and activities for children.

The museum sits on the rural east side of Antelope Valley, reached by a road off the highway; the grounds include a self-guided nature trail, a picnic area and an outdoor ceremonial arena. The chalet-style building is built over the rock of Piute Butte, so expect uneven footing and stairs between levels. Allow time for both the indoor exhibits and the trail.

The museum building was raised in 1928 by homesteader and artist H. Arden Edwards directly over a rock formation of Piute Butte, so the chalet-style house and its exhibits wrap around the stone. The structure, first a family home, is listed on the National Register of Historic Places.
