Discovery Bay is a census-designated place (CDP) in extreme eastern Contra Costa County, California in the United States about 60 miles (97 km) from San Francisco. As of 2010, its population was 13,352.

Discovery Bay is based on a waterfront community of 3,500+ homes with private docks with access to the Sacramento-San Joaquin River Delta. Discovery Bay has added Discovery Bay West, which consists of gated and non-gated "off-water" communities with homes from 1,400 square feet (130 m²) up to 4,700 square feet (440 m²).^{[citation needed]}

In July 2007, Discovery Bay celebrated its maturity into its own community by changing the ZIP code from 94514 (which it shared with the neighboring community of Byron) to 94505. A huge town celebration ensued with a world record-setting paddle boat raft-up.
