Romania is a country in Southeastern Europe. Romania borders Hungary and Serbia to the west, Ukraine and Moldova to the northeast, and Bulgaria to the south, mostly along the Danube River. Romania has a stretch of sea coast along the Black Sea, and the eastern and southern Carpathian Mountains run through its center. Historic Bucharest is its capital.

A large part of Romania's borders with Serbia and Bulgaria is formed by the Danube. The Danube is joined by the Prut River, which forms the border with Moldova. The Danube flows into the Black Sea forming the Danube Delta which is a reservation of the Biosphere.

The Carpathian Mountains dominate the centre of Romania surrounding the Transylvanian Plateau, 14 peaks reaching above the altitude of 2,000 metres (6,560 ft), the highest being Moldoveanu Peak. Its main cities are the capital Bucareste, Braşov, Timişoara, Cluj-Napoca, Constanţa, Craiova, Iaşi, Brăila e Galaţi
