The Yakima Indian Agency Building, also known as the Mary L. Goodrich Library and the Toppenish Historical Museum, is a building in Toppenish, Washington. It was built in 1921, initially as a one-story building, with a second story added in 1931. It was designed by Yakima architect John W. Maloney in an adapted Classical Revival style for the federal Indian Bureau as the agency's point of liaison with the Yakama Nation. By 1946 the structure was vacated by the Indian Bureau, and it was sold to the local school district in 1949 and was used as a junior high school until 1954. In 1954 it became a library, to which a museum of local history was added in 1976.
