Dalmatia  is the southern coastal region of Croatia on the Adriatic Sea.
Dalmatia is traditionally divided into three subregions, along the coast
- Northern Dalmatia has lots of small islands and deep, connected inland. This subregion corresponds to Zadar county and Sibenik-Knin county of Croatia.
- Central Dalmatia has several bigger islands (like Brač and Hvar), with mountains close to coast (like Biokovo) and somewhat separated inland. It is administrated as Split-Dalmatia county of Croatia.
- Southern Dalmatia is a narrow strip of land around Dubrovnik, with weak connection to inland (Herzegovina, in another country Bosnia and Herzegovina). It roughly corresponds to the Dubrovnik-Neretva county of Croatia.
Most travelers come in through the new highway A1 Zagreb-Split. As of summer 2005, it finally connects these two Croatian cities, as well as the North Dalmatian coast. The highway is modern, fast and safe, but often becomes congested on weekends during holidays and in the summer at the tunnel of Sveti Rok.
Split and Dubrovnik have international airports and seaports.
