Herbert Maier (January 2, 1893 – February 23, 1969) was an American architect and public administrator, most notable as an architect for his work at Yosemite, Grand Canyon and Yellowstone National Parks. Maier, as a consultant to the National Park Service, designed four trailside museums in Yellowstone, three of which survive as National Historic Landmarks. Maier played a significant role in the Park Service's use of the National Park Service Rustic style of architecture in western national parks.
