Republika Srpska is one of the two political entities that compose Bosnia and Herzegovina, the other being the Federation of Bosnia and Herzegovina. Situated in the northern and eastern parts of the country, it is defined by its rich natural heritage, encompassing dense forests, mountains, and rivers. Its largest city and de facto capital, on the river Vrbas, is Banja Luka.
Situated in Southeast Europe, Republika Srpska is located on the Balkan Peninsula, with its northern extents reaching into the Pannonian Basin.
Republika Srpska is one of the most forested areas in Europe, with over 50% of its area consisting of forest cover. Perućica is one of the last old-growth forests in Europe.
Two densely-wooded national parks—Sutjeska National Park and Kozara National Park—are located in the entity.
Most rivers belong to the Black Sea drainage basin. The principal rivers are the Sava, a tributary of the Danube that forms the northern boundary with Croatia; the Bosna, Vrbas, Sana and Una, which flow north and empty into the Sava; the Drina, which flows north, forms part of the eastern boundary with Serbia, and is also a tributary of the Sava. The Trebišnjica is one of the longest sinking rivers in the world. It belongs to the Adriatic Sea drainage basin. Skakavac Waterfall on the Perućica is one of the highest waterfalls in the country, at about 75 metres (246 feet) in height. The most important lakes are Bileća Lake, Lake Bardača (which includes a protected wetland area) and Balkana Lake.
