Rancho Rincón de los Esteros

Rancho Rincón de los Esteros was a 6,353-acre (25.71 km2) Mexican land grant in present-day Santa Clara County, California.

It was given by Governor Juan Bautista Alvarado in 1838 to Ignacio Alviso. The name means Estuaries Corner or Estuaries Bend, in reference to the local estuaries.

The ranch was located within the present day Santa Clara County, on the southern shore of San Francisco Bay between the Guadalupe River and Coyote Creek outflows.
