The Bihor County Administrative Palace (Palatul Administrativ al Județului Bihor) is a historical building facing Trajan Park (Parcul Traian) in the historical center of Oradea, Bihor County. The building houses the Bihor County Prefecture (Prefectura Județului Bihor) and the Bihor County Council (Consiliul Județean Bihor).
The historical monument was built in a Baroque style in 1760, when the county included a larger territory, including a part that now belongs to Hungary. In 1855, a rehabilitation took place following the plans of the architect Kálmán Rimanóczy sr., during which many of the Baroque elements were removed from the facade.
