Oradea is a city in Romania, located in the Crișana region. The seat of Bihor County, Oradea is one of the most important economic, social and cultural centers in the western part of Romania. The city is located in the north-west of the country, nestled between hills on the Crișana plain and situated on the banks of the river Crișul Repede that divides the city into almost equal halves.

Crișana is a geographical and historical region in north-western Romania, named after the Criș (Körös) River and its three tributaries: the Crișul Alb, Crișul Negru, and Crișul Repede. In Romania, the term is sometimes extended to include areas beyond the border, in Hungary; in this interpretation, the region is bounded to the east by the Apuseni Mountains, to the south by the Mureș River, to the north by the Someș River, and to the west by the Tisza River, the Romanian-Hungarian border cutting it in two. However, in Hungary, the area between the Tisza River and the Romanian border is usually known as Tiszántúl.
