Barrancabermeja (Spanish: [baraŋkaβeɾˈmexa]) is a municipality and city in Colombia, located on the shore of the Magdalena River, in the western part of the department of Santander.

In the past a Ferry service would cross between Santander and Antioquia, on the opposite side, where further oil fields are found.

Barrancabermeja has a tropical monsoon climate (Am) with heavy rainfall in all months except January.

Barrancabermeja's culture has been largely affected by the migratory movements caused by the oil boom.

The commercial area of the city is adjacent to the river port ("the Port") where motor boats and canoes constantly arrive with fish and agricultural products from farmers along the river that include maize, cassava (or yuca in Spanish), plantain, and cacao.
