German Grosswardein, Hungarian Nagyvarad,

city, capital of Bihor judet (county), northwestern Romania. It lies about 8 miles (13 km) east of the Hungarian border, along the Crisul Repede River where it leaves the western foothills of the Western Carpathians and flows onto the Hungarian Plain.

One of the first feudal states in the area, a principality ruled by Prince Menumorut in the 9th-10th century, was centered on a citadel at Biharea, northwest of Oradea. The citadel of Oradea was erected between 1114 and 1131,destroyed by the Tatars in 1241, and rebuilt in the 15th century under the Corvinus dynasty. Between 1660 and 1692 the community was occupied by the Turks; it then became Hungarian until ceded to Romania in 1919.

Oradea is a cultural centre, with a state theatre, puppet theatre, philharmonic orchestra, regional library, and museum.

Five miles east of Oradea are the spas of Baile 1 Mai (Baile Felix) and Baile 9 Mai (Baile Victoria).

Since World War II, Oradea has become a major industrial centre, producing machine tools, electronic equipment, chemicals, processed foods, and footwear.
