The Caribbean Bloc of the FARC-EP was a medium-sized FARC-EP bloc which operated in the northern areas of Colombia and along the Caribbean coast, with routes and access to the coast being strategically important, and was thus sometimes referred to as the Northern Bloc. At the end of the 1990s the group had much control over the rural areas connecting the urban centers of the Caribbean region, but in the 2000s was forced to retreat into the more inhospitable Andes. The group's leaders have been held responsible for numerous kidnappings and killings along the entire Caribbean coast, including the urban centers Cartagena, Barranquilla, Valledupar and Santa Marta. This bloc was also the center of the high-profile kidnapping of Fernando Araújo, who recovered his freedom during a Colombian National Army offensive in early 2007.
The specific divisions of the group are arguable. Some of the believed divisions or "fronts", as they were commonly call them, are shown below. Many of these fronts sometimes worked together towards a certain mission, while others were further divided into "columns" and "companies" with a smaller number of members.
