Adolfo Camarillo, (October 28, 1864 – December 10, 1958) was a prominent land owner, horse breeder, rancher, and philanthropist in the late 19th and early 20th centuries in Ventura County area of California, U.S.A.  Adolfo, along with his brother Juan, Jr., owned much of what later became the town known by their family name, Camarillo. Adolfo 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. In addition because of Adolfo’s philanthropy in 1950, Pope Pius XII named Adolfo a Knight of St. Gregory the Great.
