Rancho San Francisco de las Llagas was a 22,283-acre (90.18 km2) Mexican land grant in present-day Santa Clara County, California given in 1834 by Governor José Figueroa to Carlos Antonio Castro.
In 1812, Carlos Castro was mayor domo of Mission Santa Cruz, and received the six square league Rancho San Francisco de las Llagas grant in 1834.
In 1848, the heirs of Carlos Castro sold Rancho San Francisco de las Llagas to Martin Murphy's sons Daniel and Bernard.
Daniel Murphy Jr. sold his land on Rancho San Francisco de las Llagas in 1892 to real estate developer Chauncey Hatch Phillips.
Bernard Murphy was killed in the explosion of the steamboat "Jenny Lind" en route from Alviso to San Francisco on April 11, 1853, and his wife Catherine inherited the land.
