The Richmond District is a neighborhood in the northwest corner of San Francisco, California, developed initially in the late 19th century. It is sometimes confused with the city of Richmond, which is 20 miles (32 km) northeast of San Francisco.

The Richmond is in many ways defined by its relation to the parks; the district is bordered by Golden Gate Park on the south, the Pacific Ocean to the west, and Lincoln Park, Land's End, Mountain Lake Park and the Presidio of San Francisco to the north, bisected by the Presidio Greenbelt.

One of its three commercial strips, Clement Street in the Inner Richmond segment, is sometimes called the second Chinatown due to the high concentration of Chinese establishments. The other two commercial strips are Geary Boulevard and Balboa Street.

The neighborhood was given its name by Australian immigrant and art dealer George Turner Marsh, one of the neighborhood's earliest residents, who called his home "the Richmond House" after Richmond, a suburb of Melbourne, Australia. In 1917, the district was legally named "Park-Presidio District", chosen to avoid confusion between the district and the city of Richmond right across the bay. In spite of the official change, virtually every San Franciscan continued to use the old name.

The Richmond has been popularly divided into four parts:

Lake Street is just south of Presidio of San Francisco and north of Inner Richmond. It is an affluent area characterized by its many Victorian/Edwardian mansions. Its boundaries are: the Presidio to the north, Arguello Blvd to the east, California St. to the south, and 25th Ave. to the west. Its name is derived from its proximity to Mountain Lake, one of the few remaining natural lakes in San Francisco, and Lake Street, the neighborhood's northernmost east–west artery. Spanish explorer Juan Bautista de Anza ended his second northward expedition at the lake, stopping for two days in 1776. While here he located a site for the Spanish presidio that was later built. A plaque was placed in September 1957 near the point where he stayed.

Inner Richmond sits south of Lake Street. Its boundaries are: California St. to the north, Arguello Blvd to the east, Fulton St. to the south, and Park Presidio Blvd. to the west. The hub of the Inner Richmond is Geary Blvd & Clement St, which are particularly known for Chinese, Cambodian, Korean, Burmese, and Russian cuisine. The Inner Richmond is a diverse area with sizable Chinese and Russian populations.

Central Richmond is between Inner Richmond (to the east) and Outer Richmond (to the west). It is bounded by Park Presidio Blvd to the east, California St. to the north, Fulton St. to the south, and 32nd Ave. to the west. Its hub is on Geary Blvd. (between Park Presidio Blvd. to 28th Avenue).

Outer Richmond is to the west of the Central Richmond. It is bounded by Clement St. to the north, 32nd Ave. to the east, Fulton St. to the south, and Ocean Beach to the west. It borders the Ocean Beach and the Cliff House, currently operating as a restaurant. Lincoln Manor is a small enclave of larger homes within the Outer Richmond. It includes a vibrant merchant corridor on the western portion of Balboa St. from approximately 32nd Ave. to 42nd Ave. called Balboa Village.
