José Agustín Olachea Avilés (September 3, 1890 – April 13, 1974) was a Mexican general[1] who supported Lázaro Cárdenas for president.[2] During the Cárdenas years he served as Governor of the Federal North Territory of Baja California, having previously filled the same post for Baja California Sur as a member of the social-democratic Institutional Revolutionary Party. This second gubernatorial term came during a period of rising hostility toward the Chinese population in Mexicali.[3] Later, Olachea Avilés acted as Secretary of Defense under Adolfo López Mateos.[4]
In 1946, he was re-elected to a second, ten-year term as Governor of Baja California Sur.
While still a young captain in the Mexican Armed Forces, Olachea Avilés had married 16-year-old Ana María Borbón Yañez (1898-1982) in Guadalajara, Jalisco, with whom he had children.
He was himself, through the paternal line, a second-generation Mexican of Basque descent, and a member of an extensive family still scattered across the Baja California Peninsula and in parts of Southern California.
