Rafael Aguilar Guajardo (died 1992) was a Mexican drug lord, former police commander and one of the founders of the Juárez cartel.
A commander of the Chihuahua State Police, he had several police officers take part in Pablo Acosta's drug smuggling ring. By 1986, he acted as Acosta's second-in-command along with Amado Carrillo Fuentes and was a part of the Guadalajara cartel.
In 1989, he and Carrillo Fuentes founded the Juárez cartel. However the partnership didn't last long as Carrillo Fuentes was fed up with Aguilar's miserly methods of running the cartel. After Aguilar refused to allow Carlos Hank González to expand his business interests into Ciudad Juárez, Amado killed Aguilar and struck a deal with Hank.
