Reghin (Romanian pronunciation: [ˈreɡin]; Hungarian: Szászrégen, Hungarian pronunciation: [ˈsaːsreːɡɛn] or Régen; German: (Sächsisch) Regen) is a city and municipality in Mureș County, Transylvania, Romania, on the Mureș River. As of 2011 it has a population of 33,281.
Reghin lies 29 km north-northeast of Târgu Mureş, extending on both shores of the Mureş River, at the confluence with the Gurghiu River. It was created by the 1926 union of the German-inhabited (formerly Szászrégen) and the Hungarian-inhabited (formerly Magyarrégen) city, and later joined with the two smaller communities of Apalina (Hungarian: Abafája; German: Bendorf) and Iernuţeni (Hungarian: Radnótfája; German: Etschdorf), added in 1956. Formally, the latter two are separate villages administered by the city.
Reghin was first mentioned in 1228 in a charter of Hungarian King Andrew II as Regun - however, evidence of its strategic location and defence system suggests that the town might have been considerably older, possibly founded by Ladislaus I.
