La Oficina de Envigado (English: The Office of Envigado) is a drug cartel and criminal organization originally founded as an enforcement and collections arm of Pablo Escobar's Medellin Cartel. It operates throughout Colombia, but mainly in the cities of Medellín and Envigado. It also controls extortion, gambling, and money laundering businesses within the Valle de Aburra that surrounds Medellin. It positioned itself as the chief mediator and debt collector in drug trafficking disputes and maintained major connections with the paracos (Colombian paramilitaries) and guerillas.
