Atlántico Department in the context of Canal del Dique

The Caribbean region of Colombia or Colombian Caribbean is the northern, coastal region of Colombia located contiguous to the Caribbean. It is mainly composed of 8 departments. It is the second most populated region in the country after the Andean Region with approximately 11 million residents according to the Colombian Census 2018. The area covers a total land area of 110,000 km (42,000 sq mi), including the Archipelago of San Andrés, Providencia and Santa Catalina in the Caribbean Sea.

The Caribbean region coast extends from the Gulf of Urabá to the Gulf of Venezuela. Straddling the coast are Colombia's two main Atlantic port cities of Barranquilla and Cartagena. The administration of the region is covered by eight department governments: Atlántico, Bolívar, Cesar, Sucre, Córdoba, Magdalena, La Guajira and San Andrés and Providencia. These eight departments also cover approximately 182 municipalities according to the 2018 Census by DANE Colombia. Most of its inhabitants speak a dialect of Caribbean Spanish with variations within its subregions.

Puerto Colombia is a coastal town and municipality in Atlántico Department, Colombia founded in the mid-1800s. It is famous for its "Pier of Puerto Colombia", that at one time was the largest pier in the world. Duties were later transferred to the larger and modern Port of Barranquilla in Bocas de Cenizas, the mouth of the Magdalena River in the Caribbean Sea.

The town enjoyed a glorious post-colonial period as the main port on the Caribbean coast of Colombia, where most European immigrants entered the country. In the second half of the 20th century, Puerto Colombia faced a rapid decline, eclipsed by Barranquilla, the capital of Atlántico.

It is located to the north of the country, extending roughly north–south from the Caribbean coast at Cartagena near the mouth of the Magdalena River, then south along the river to a border with Antioquia Department. The departments of Sucre and Córdoba are located to the west, and Atlántico Department to the north and east (most of the border formed by the Canal del Dique). Across the Magdalena River to the east is Magdalena Department. The flag of the department bears a resemblance to the flag of Lithuania.

Its capital is Cartagena de Indias. Other important cities include Magangué, El Carmen de Bolívar and Turbaco.
