San Francisco Bay is a multi-county American Viticultural Area (AVA) which is centered and surrounds the San Francisco Bay Area of Northern California. It was established on January 19, 1999 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after evaluating the petition submitted by a consortium of nearly 75 growers and vintners led by Wente Bros. to establish the viticultural area known as "San Francisco Bay." It lies within the larger Central Coast viticultural area and includes San Francisco and counties encompassing the areas known as “South” and “East Bay.” This consists of Alameda, Contra Costa, Santa Clara, and San Mateo as well as portions of Santa Cruz and San Benito Counties. “North Bay” counties of Sonoma, Napa and Marin were excluded for they reside within the North Coast viticultural area with its distinct properties. ATF also concluded the established Santa Cruz Mountains viticultural area exhibits features and characteristics unique to its boundaries when compared to the surrounding areas, therefore, it was excluded from the "San Francisco Bay" viticultural area.

The San Francisco Bay Area, which includes the major cities of San Jose, San Francisco, and Oakland, was an early center of the COVID-19 pandemic in California. The first case of COVID-19 in the area was confirmed in Santa Clara County on January 31, 2020. A Santa Clara County resident was the earliest known death caused by COVID-19 in the United States, on February 6, suggesting that community spread of COVID-19 had been occurring long before any actual documented case.
