The Bojana or Buna (Albanian: Bunë or Buna; Montenegrin and Serbian: Бојана, Bojana) is a 41 km long river in Albania and Montenegro which flows both into the Adriatic Sea. An outflow of Lake Skadar, measured from the source of the lake's longest tributary, the Morača, the Morača-Lake Skadar- Bojana system is 183 km long.
The river used to be longer, but due to a rise in the level of Lake Skadar, the uppermost part of the river is now under the lake's surface. The river initially flows east, but after only few kilometers reaches the city of Shkodër and turns to the south. On the southern outskirts of the city, the river receives its most important tributary, the Great Drin, the greater part of which became its tributary after changing course during a flood in 1858 and now brings ten times more water than the Bojana itself (320 m³/s). After flowing around the Peak of Tarabosh, it passes through the villages of Zues, Bërdicë, Darragjat, Oblikë, Obot, Shirq, Dajç and Goricë.
The Buna is a short river in Bosnia and Herzegovina; it is a left bank tributary of the Neretva. Its source (Vrelo Bune), a strong karstic spring, is near the village Blagaj, southeast of Mostar. Actually, it is best known by famous Buna Spring (Vrelo Bune), one of the strongest spring in Europe and extremely cold water. The Buna flows west for approximately 9 km, starts at Blagaj and meandering through villages Blagaj, Kosor, Malo Polje, Hodbina and joins the Neretva at Buna village. The Bunica river is main left bank tributary of the Buna.
