Adolfo Camarillo (October 29, 1864 – December 10, 1958) was a prominent Californio land owner, horse breeder, rancher, and philanthropist in the late 19th and early 20th centuries in the Oxnard Plain area of Ventura County, California in the United States.
Camarillo, along with his brother Juan Jr., owned much of what later became the town known by their family name, Camarillo.
Camarillo also donated the land for Adolfo Camarillo High School.
The horse breed Camarillo White Horse was named for Camarillo.
He began breeding them in 1921 and the line continues today.
Because of his philanthropy in 1950, Pope Pius XII named him a Knight of St.
