Lake Berryessa is the largest lake in Napa County, California, United States. This reservoir in the Vaca Mountains was formed following the construction of the Monticello Dam on Putah Creek in the 1950s. Since the early 1960s, this reservoir has provided water and hydroelectricity to the North Bay region of the San Francisco Bay Area.

The reservoir was named after the Berryessa family of California; José Jesús and Sexto "Sisto" Berryessa were granted Rancho Las Putas in 1843.
