The Bixby family is an American family that was heavily involved in the development of California ranches and real estate in the 19th and 20th centuries. Through various companies, they controlled at one time or another large swathes of California real estate, much of it derived from Mexican land grants. Over several generations, their holdings included Rancho Los Cerritos and Rancho Los Alamitos, and parts of Rancho San Justo and Rancho Palos Verdes, totaling well over 100,000 acres. Parts of the towns of Long Beach, Bellflower, Paramount, Signal Hill, Lakewood, and Los Alamitos emerged from former Bixby-held lands. Within Long Beach, the neighborhoods Bixby Hill, Bixby Knolls, and Bixby Village are named after the family, as well as Bixby Park in the Alamitos Beach neighborhood.
