Los Rastrojos is a Colombian drug cartel and paramilitary organization involved in the Colombian armed conflict. The group originated around 2004 following a dispute between Norte del Valle cartel capo Wilber Varela, known as "Jabón," and his associate Diego Leon Montoya, alias "Don Diego." It was founded by Varela and one of his primary associates, "Diego Rastrojo."
The organization became independent following the murder of its main founder in Venezuela in 2008. At its peak, Los Rastrojos was recognized as one of the most significant drug trafficking organizations operating within Colombia.
