Belvedere is a small, very affluent city in Marin County, California, United States, located 1.5 miles northeast of Sausalito. Situated on two islands, it is immediately adjacent to the Tiburon Peninsula, accessible via a short bridge from the city of Tiburon. At the 2010 census, the population was 2,068 and the per-capita income in 2000 was $250,000, making it one of the highest income cities in California and the 8th highest income place in the United States.

Situated on the Tiburon Peninsula at the southeastern base of Ring Mountain, between Richardson Bay and the Town of Tiburon, Belvedere consists of two “islands” and the lagoon (Belvedere Lagoon) between them. The larger of the two islands is Belvedere Island, and the smaller one is Corinthian Island, which is shared with Tiburon. The area of Ring Mountain is notable for its archaeological resources of extant Native American petroglyphs as well as considerable biodiversity of California native plants.

The city sits on the south side of the tip of Tiburon Peninsula, a small peninsula that extends into San Francisco Bay. Many Belvedere properties are renowned for their spectacular views of the Bay Area, Angel Island, San Francisco, Sausalito, the Golden Gate Bridge and Mount Tamalpais. Many houses in Belvedere are in the Victorian style of architecture. Some Belvedere homes are featured on “The Home Tour” every May.

No restaurants or stores are allowed in Belvedere, and the city enforces strict rules regarding house design and setbacks in order to preserve trees, views and the town’s spacious, wooded character. The adjacent town of Tiburon, however, is home to a wide range of services, shops and eateries. Originally a fishing-based community, Belvedere has grown into a sailing community where the San Francisco Yacht Club is located. Belvedere Park is also located in Belvedere.
