Map - Sfântu Gheorghe (Municipiul Sfântu Gheorghe)

Sfântu Gheorghe (Sepsiszentgyörgy or Szentgyörgy ; סנט דזשארדזש; English lit.: Saint George) is the capital city of Covasna County, Romania. Located in the central part of the country and in the historical region of Transylvania, it lies on the Olt River in a valley between the Baraolt Mountains and Bodoc Mountains. The city administers two villages, Chilieni (Kilyén) and Coșeni (Szotyor).

Sfântu Gheorghe is one of the oldest cities in Transylvania, the settlement first having been documented in 1332. The city takes its name from Saint George, the patron of the local church. Historically it was also known in German as Sankt Georgen. The "sepsi" prefix (sebesi → sepsi, meaning "of Sebes") refers to the area which the ancestors of the local Székely population had inhabited before settling to the area of the town. The previous area of their settlement was around the town of "Sebes" (now: Sebeș) which later became populated mainly by Transylvanian Saxons.

While part of the Kingdom of Hungary, the city was the economic and administrative center of the Hungarian county of Háromszék, which spanned the present-day Covasna County and parts of Brașov County. In the second half of the 19th century, Sepsiszentgyörgy witnessed the development of light industry, namely a textile and a cigarette factory was built. It became part of the Kingdom of Romania following the Treaty of Trianon in 1920, after the end of World War I. After the Second Vienna Award in 1940 the city came under Hungarian control for four years. Near the end of that period, the Sfântu Gheorghe ghetto briefly existed in the city. At the end of the Second World War the Paris Peace Treaties reaffirmed the city and the entirety of Transylvania as a Romanian territory. Between 1952 and 1960 it was the southernmost town of the Magyar Autonomous Region, and between 1960 and 1968 was part of the Brașov Region, abolished in 1968 when Romania was reorganised based on counties rather than regions.

Sfântu Gheorghe is one of the centres for the Székely people in the region known to them as Székelyföld in Hungarian – which means "Székely Land", and is home to the Székely National Museum. The city hosts two market fairs each year.
