Raúl Alberto Trejo Benavides (died 13 May 2002) was a Mexican suspected drug lord and high-ranking member of Los Zetas, a criminal group based in Tamaulipas, Mexico. Trejo Benavides served in the Mexican Army from 1991 to 1999, and was a member of the Grupo Aeromóvil de Fuerzas Especiales (GAFE), the army's special forces. He joined the Gulf Cartel under kingpin Osiel Cárdenas Guillén after leaving the army, becoming one of the first members of its newly formed paramilitary wing, Los Zetas. Like Trejo Benavides, most of the first members of Los Zetas were ex-military. Los Zetas was responsible for providing security services to Cárdenas Guillén and carrying out executions on the cartel's behalf.
