San Francisco's Sunset District neighborhoods include Golden Gate Heights, Inner Sunset, Outer Sunset, Parkside, and Parnassus Heights.

The Sunset District is the largest neighborhood within the city and county of San Francisco. Golden Gate Park forms the neighborhood's northern border, and the Pacific Ocean (or, more specifically, the long, flat strand of beach known as Ocean Beach) forms its western border. A section of the Sunset District towards its southeastern end is known as the Parkside neighborhood. Prior to the residential and commercial development of the Sunset District, much of the area was covered by sand dunes and was originally referred to by 19th century San Franciscans as the "Outside Lands.

The Sunset District and the neighboring Richmond District (on the north side of Golden Gate Park) are often collectively known as The Avenues, because the majority of both neighborhoods are spanned by numbered north-south avenues. When the city was originally laid out, the avenues were numbered from 1st to 49th, and the east-west streets were lettered A to X. In 1909, to reduce confusion for mail carriers, the east-west streets and 1st Avenue and 49th Avenue were renamed. The east-west streets were named in ascending alphabetical order in a southward direction after prominent 19th-century American politicians, military leaders, or explorers; 19th-century Mexican landowners; and Spanish conquistadors. 1st Avenue was renamed Arguello Boulevard, and 49th Avenue was renamed La Playa Street (Spanish for "the beach").

Sand, scrub, and more sand. Such was the foundation of the Sunset District.
