Rancho Niguel was a 13,316-acre (53.89 km2) Mexican land grant in the San Joaquin Hills, within present-day Orange County, California.
It was granted in 1842 by Governor Juan B. Alvarado to Juan Avila.[1] The rancho was named for a local Indian village called "Niguili." The grant extended along the Pacific coast from Laguna Canyon and Laguna Beach, past Aliso Creek to Dana Point and San Juan Creek. The rancho encompassed those present-day places and Laguna Niguel, Aliso Viejo, and Laguna Hills.[2][3]
