The BuzÃÂu river () in eastern Romania is a tributary of the river Siret. Its total length is 302 km, and its drainage basin area is 5,264 km<sup>2</sup>. Its source is in the south-eastern Carpathian Mountains, east of BraÃÂov. The BuzÃÂu flows through the Romanian counties BraÃÂov, Covasna, BuzÃÂu and BrÃÂila. It flows into the Siret in VoineÃÂti, close to its confluence with the Danube, west of GalaÃÂi.
The river BuzÃÂu gives its name to two urban municipalities: the city of BuzÃÂu (the BuzÃÂu county seat) and the town of ÃÂntorsura BuzÃÂului, in Covasna County. ÃÂntorsura BuzÃÂului (which means BuzÃÂu's Turning in Romanian) gets its name from being located near a large turn that the river takes. It initially flows northwards, but takes a sudden turn towards the south-east near the town.
