Antioch, city, Contra Costa county, western California, U.S. Lying on the San Joaquin River, it was founded as Smith’s Landing in 1849.

Many national manufacturers have large plants there, producing paper and fibreboard, chemicals, and steel. The city hosts an annual jamboree and a blues festival. Antioch Dunes National Wildlife Refuge, which was closed to the public for 16 years, protects the habitat of several endangered species.
