Dubrovnik, historically known as Ragusa, is a city in southern Dalmatia, Croatia, by the Adriatic Sea.

It is one of the most prominent tourist destinations in the Mediterranean, a seaport and the centre of the Dubrovnik-Neretva County.

Dubrovnik has a total population of 42,615 (according to the 2011 census). In 1979, the city of Dubrovnik was added to the UNESCO list of World Heritage Sites in recognition of its outstanding medieval architecture and fortified old town.

The history of the city probably dates back to the 7th century, when the town known as Ragusa was founded by refugees from Epidaurum (Ragusa Vecchia). It was under the protection of the Byzantine Empire and later under the sovereignty of the Republic of Venice. Between the 14th and 19th centuries, Dubrovnik ruled itself as a free state. The prosperity of the city was historically based on maritime trade; as the capital of the maritime Republic of Ragusa, it achieved a high level of development, particularly during the 15th and 16th centuries, as it became notable for its wealth and skilled diplomacy. At the same time, Dubrovnik became a cradle of Croatian literature.

The entire city was almost destroyed when a devastating earthquake hit in 1667.

In 1991, during the Croatian War of Independence, Dubrovnik was besieged by the Yugoslav People's Army for seven months and suffered significant damage from shelling. After undergoing repair and restoration works in the 1990s and early 2000s, it re-emerged as one of the Mediterranean's top tourist destinations, as well as a popular filming location.

Dubrovnik's international airport is located approximately 20 km (12 miles) southeast of Dubrovnik city centre, near Čilipi. Buses connect the airport with the Dubrovnik old main bus station in Gruž. In addition, a network of modern, local buses connects all Dubrovnik neighbourhoods running frequently from dawn to midnight. However, Dubrovnik, unlike Croatia's other major centres, is not accessible by rail; until 1975 Dubrovnik was connected to Mostar and Sarajevo by a narrow gauge railway (760 mm) built during the Austro-Hungarian rule of Bosnia.

The A1 highway, in use between Zagreb and Ploče, is planned to be extended all the way to Dubrovnik. Because the area around the city is disconnected from the rest of Croatian territory, the highway will either cross the Pelješac Bridge whose construction was completed in 2022, or run through Neum in Bosnia and Herzegovina and continue to Dubrovnik.

The HBO series Game of Thrones used Dubrovnik as a filming location, representing the cities of King's Landing and Qarth.

Did you know that parts of Star Wars: The Last Jedi were filmed in Dubrovnik in March 2016, in which Dubrovnik was used as the setting for the casino city of Canto Bight.
