Rancho Tequepis was a 8,919-acre (36.09 km2) Mexican land grant in present day Santa Barbara County, California given in 1845 by Governor Pio Pico to Joaquin Villa. The grant extended along both sides of the Santa Ynez River at the mouth of Cachuma Creek east of present day Santa Ynez. Much of the grant is now under the waters of Lake Cachuma which was formed in 1953.
With the cession of California to the United States following the Mexican-American War, the 1848 Treaty of Guadalupe Hidalgo provided that the land grants would be honored. As required by the Land Act of 1851, a claim for Rancho Tequepis was filed with the Public Land Commission in 1852, and the grant was patented to Joaquin Villa's son, Antonio Maria Villa (1829–1899) in 1869.
