Cardinal Juan Jesús Posadas Ocampo (11 November 1926, in Tarimoro, Guanajuato – 24 May 1993, in Guadalajara, Jalisco) was a Mexican bishop of the Catholic Church who served as the eighth archbishop of the see of Guadalajara and as a cardinal of the Roman Catholic Church.
Posadas Ocampo was elevated to the cardinalate by Pope John Paul II on the consistory of June 28, 1991.
On May 24, 1993, Posadas Ocampo, along with six other people, was assassinated in the parking lot of Guadalajara International Airport. He was inside his car and received 14 gunshots. A government inquiry concluded he was caught in a shootout between rival cocaine cartels and was mistakenly identified as a drug lord, but no one was ever imprisoned for the slaying itself, although charges related to the homicide would be filed. Juan Francisco Murillo Díaz "El Güero Jaibo" and Édgar Nicolás Villegas "El Negro", members of the Tijuana Cartel, were identified as the masterminds of the homicide.
Although ordered by the Tijuana Cartel, many members of the hit squad were actually San Diego-based gang members from the Logan Heights gang; trained by the Tijuana Cartel as assassins.
