Rancho Punta de Laguna was a 26,648-acre (107.84 km2) Mexican land grant in present day northern Santa Barbara County, California, and southern San Luis Obispo County given in 1844 by Governor Manuel Micheltorena to Luis Arellanes and Emigdio Miguel Ortega. The name of this rancho means "point of the lagoon" and refers to the irregular lake lying within its territory. The grant is east of Rancho Guadalupe and encompasses present day Santa Maria and Betteravia.
