The city of Buzău (formerly Buzeu, or Buzĕu; Romanian pronunciation: [buˈzəw]) is the county seat of Buzău County, Romania, in the historical region of Wallachia. It lies near the right bank of the Buzău River, between the south-eastern curvature of the Carpathian Mountains and the lowlands of Bărăgan Plain.

The city's name dates back to 376 AD when the name appeared on a letter that spoke about the martyrdom of Sabbas the Goth. During the Middle Ages, Buzău was as an important Wallachian market town and Eastern Orthodox episcopal see. It faced a period of repeated destruction during the 17th and 18th century, nowadays symbolized on the city seal by the Phoenix bird. Those destructions are the main reason for which no building older than the 18th century exists in the city. After that, Buzău slowly recovered to become nowadays an important modern city in south-eastern Romania.

The city's landmark building is the Communal Palace, located in the central Dacia Square. The Nicolae Bălcescu Boulevard links it to the Crâng park, Buzău's main recreational area.
