Covasna (Romanian pronunciation: [koˈvasna] ⓘ, Hungarian: Kovászna, Hungarian pronunciation: [ˈkovaːsnɒ] ⓘ, German: Kowasna) is a town in Covasna County, Transylvania, Romania, at an altitude of 550–600 m (1,800–1,970 ft).

There are several theories regarding the origin of the city's name, the most recognized one being that it originates from the Slavic kvas, which means "bitter", referring to the taste of the mineral water springs located in the city.

[citation needed] According to Szabó Gyula (1914–1984), some legends suggest that the name of Kovászna might have been the result of a fusion between the name of "Kó" and the word "vászon" (it means canvas in Hungarian), thus meaning "Kó's canvas".

Theories suggest that the individual of "Kó" might have been a knight, a craftsman or even the last monarch of the Fairies Fortress.

[citation needed] At the 2021 census, Covasna had a population of 9,208; of those, 60.34% were Hungarians and 31.14% were Romanians.
