Munson Valley Historic District is the headquarters and main support area for Crater Lake National Park in southern Oregon. The National Park Service chose Munson Valley for the park headquarters because of its central location within the park. Because of the unique rustic architecture of the Munson Valley buildings and the surrounding park landscape, the area was listed as a historic district on the National Register of Historic Places (NRHP) in 1988. The district has eighteen contributing buildings, including the Crater Lake Superintendent's Residence which is a U.S. National Historic Landmark and separately listed on the NRHP. The district's NRHP listing was decreased in area in 1997.

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.
