The Dubrovnik - Neretva County is the southernmost county in the Republic of Croatia. It encompasses an area of 1785 km2 and has about 127,000 residents. The specificity of the Dubrovnik - Neretva County is in its narrow and heterogeneous coastline, separated from the interior by a mountain range, and divided at Neum by the state border with Bosnia Herzegovina, while it has a natural connection to the interior and the northern Pannonic part of Croatia in the area of the Lower Neretva Valley.

Thus, the territory of the county is comprised of two basic entities: the relatively narrow coastal area with its series of islands near the mainland and in the open sea (the most significant of which are the islands of Korcula, Mljet, Lastovo and those in the Elaphite archipelago), and the Lower Neretva Valley with its coastline.

Territorially, it is organized into 22 local self-administration units, divided into 5 cities (Dubrovnik, Korcula, Ploce, Metkovic and Opuzen) and 17 municipalities (Blato, Dubrovnik coastal region, Janjina, Konavle, Kula Norinska, Lastovo, Lumbarda, Mljet, Orebic, Pojezerje, Slivno, Smokvica, Ston, Trpanj, Vela Luka, Zazablje and Zupa Dubrovnik). The center of the county is the city of Dubrovnik.
