Constanța (Romanian pronunciation: [konˈstant͡sa]), historically known as Tomis (Greek: Κωνστάντζα or Κωνστάντια, Konstantia, Bulgarian: Кюстенджа or Констанца, Turkish: Köstence), is the oldest continuously inhabited city in Romania. It was founded around 600 BC. The city is located in the Dobruja region of Romania, on the Black Sea coast. It is the capital of Constanța County and the largest city in the region.

As of the 2011 census, Constanța has a population of 283,872, making it the fifth most populous city in Romania. The Constanța metropolitan area includes 14 localities within 30 km (19 mi) of the city, and, with 425,916 inhabitants, it is the second largest metropolitan area in Romania.

The Port of Constanța has an area of 39.26 km² (15.16 sq mi) and a length of about 30 km (19 mi). It is the largest port on the Black Sea, and one of the largest ports in Europe.

According to Jordanes (after Cassiodorus), the foundation of the city was ascribed to Tomyris the queen of the Massagetae (The origin and deeds of the Goths):

In 29 BC the Romans captured the region from the Odryses, and annexed it as far as the Danube, under the name of Limes Scythicus ("Scythian Frontier").
