The Mission District, also commonly called "The Mission", is a neighborhood in San Francisco, California, United States, originally known as "the Mission lands" meaning the lands belonging to the sixth Alta California mission, Mission San Francisco de Asis. This mission, San Francisco's oldest standing building, is located in the northwest area of the neighborhood.
The Mission District is located in east-central San Francisco. It is bordered to the east by U.S. Route 101, which forms the boundary between the eastern portion of the district, known as "Inner Mission", and its eastern neighbor, Potrero Hill. Sanchez Street separates the neighborhood from Eureka Valley (containing the sub-district known as "the Castro") to the north west and Noe Valley to the south west. The part of the neighborhood from Valencia Street to Sanchez Street, north of 20th Street, is known as the "Mission Dolores" neighborhood. South of 20th Street towards 22nd Street, and between Valencia and Dolores Streets is a distinct neighborhood known as Liberty Hill. Cesar Chavez Street (formerly Army Street) is the southern border; across Cesar Chavez Street is the Bernal Heights neighborhood. North of the Mission District is the South of Market neighborhood, bordered roughly by Duboce Avenue and the elevated highway of the Central Freeway which runs above 13th Street.
