Middle Magdalena Bloc of the FARC-EP

The Middle Magdalena Bloc of the FARC-EP () was a FARC-EP bloc, notable for its involvement in the conflict with the AUC until the latter's demobilization in 2004. After that, it became one of the Colombian army's biggest worries as FARC started once again to gain control over the territory.

The specific divisions of the group are arguable. Some of the believed divisions or 'fronts', as they were commonly called, 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.  For more general information see FARC-EP Chain of Command.
