Herbert Maier 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.

National Park Service rustic – sometimes colloquially called Parkitecture – is a style of architecture that developed in the early and middle 20th century in the United States National Park Service (NPS) through its efforts to create buildings that harmonized with the natural environment. Since its founding in 1916, the NPS sought to design and build visitor facilities without visually interrupting the natural or historic surroundings. The early results were characterized by intensive use of hand labor and a rejection of the regularity and symmetry of the industrial world, reflecting connections with the Arts and Crafts movement and American Picturesque architecture.
