Rancho Tajauta was a 3,560-acre (14.4 km2) Mexican land grant in present-day Los Angeles County, California given in 1843 by Governor Manuel Micheltorena to Anastasio Avila.

The grant encompassed present-day Willowbrook and Watts.

[2] Anastasio Avila, one of the sons of Cornelio Avila, was alcalde of Los Angeles in 1819 – 1821, and granted one square league in 1843.

With the cession of California to the United States following the Mexican-American War, the 1848 Treaty of Guadalupe Hidalgo provided that the land grants would be honored.

As required by the Land Act of 1851, a claim for Rancho La Tajauta was filed with the Public Land Commission in 1852,[3][4] and the grant was patented to Anastasio's son Enrique Avila in 1873.
