Northwest Museum of Arts and Culture, Regional art museum in Browne's Addition, Spokane, United States.

The Northwest Museum of Arts and Culture is a museum in Spokane, Washington, displaying art, historical objects, and regional collections across several gallery spaces. The complex also includes a research archive and a late-19th-century historic house that visitors can tour.

The museum was formerly known as the Cheney Cowles Museum before taking its present name. It is associated with the Smithsonian Institution and accredited by the American Alliance of Museums. Its campus grew to include the 1898 Campbell House, designed by architect Kirtland Cutter and listed on the National Register of Historic Places.

The museum holds one of the largest collections of Plateau Indian artifacts in the country, covering everyday objects, textiles, and ceremonial items. Walking through the galleries gives a concrete sense of how Plateau peoples lived and worked across generations.

The MAC campus holds five underground galleries, a café, a store, an education center, a community room, an auditorium and an outdoor amphitheater, plus the 1898 Campbell House, library and archives. The Joel E. Ferris Research Library & Archives is open by appointment, so researchers should arrange access in advance. Allow time to walk between the museum building and the house.

The historic house on the museum grounds dates to 1898 and is fully furnished, giving a clear sense of daily life for a prosperous family around the turn of the 20th century. It is one of the few surviving examples of a particular architectural style from that era in the Pacific Northwest.
