Rancho Los Nietos was one of the first, and the largest, Spanish land concession in Alta California. Located in present-day Los Angeles County and Orange County, California. Rancho Los Nietos was awarded to Manuel Nieto in 1784. The rancho remained intact until 1834, when Governor Jose Figueroa officially declared the Rancho Los Nietos grant under Mexican rule and ordered its partition into six smaller ranchos.
Today, all parts of the following places are located on what was once Rancho Los Nietos:
In 1784, Spanish governor Pedro Fages granted to Manuel Nieto, a former sergeant in the Spanish army, provisional use of all land between the Santa Ana River and the Los Angeles River from the Mission San Gabriel Arcángel to the sea.
The original grant was 300,000 acres (1,200 km2), but the San Gabriel Mission contested the Los Nietos grant on the grounds that it encroached upon the southern portion of its property. A decision in favor of the mission was reached and Rancho Los Nietos was reduced to nearly half of its original size, but still leaving Corporal Nieto with 167,000 acres (680 km2). At first it was called La Zanja, but later it was known simply as Rancho Los Nietos.
Upon Manuel Nieto's death in 1804, Rancho Los Nietos passed to his wife and four children.
The rancho remained intact until 1833, when the Nieto heirs petitioned Mexican Governor José Figueroa for a partition and distribution of the land. In 1834, governor Figueroa officially declared the Los Nietos grant under Mexican rule and ordered its partition into six smaller ranchos.
|1834 Partition of Rancho Los Nietos|
|Los Alamitos||28,612 acres (115.79 km2)||Juan Jose Nieto|
|Las Bolsas||33,460 acres (135.4 km2)||Catarina Ruiz (widow of Jose Antonio Nieto)|
|Los Cerritos||27,054 acres (109.48 km2)||Manuela Nieto de Cota and her husband Guillermo Cota|

Rancho Palo Alto was the smallest of the six ranchos. It is unknown exactly where or how large was Rancho Palo Alto as it did not appear on the partition map. It included the Coyote Hills and most of the Arroyo de los Coyotes, and may have been combined into Rancho Los Coyotes.
