Câmpulung (also spelled Cîmpulung, Romanian pronunciation: [kɨmpuˈluŋɡ]), or Câmpulung Muscel, is a city in the Argeş County, Muntenia, Romania. It is situated among the outlying hills of the Carpathian mountains, at the head of a long well-wooded glen traversed by the Râul Târgului, a tributary of the Argeş.
Its pure air and fine scenery render Câmpulung a popular summer resort. In the city there are more than twenty churches, besides a monastery and a cathedral, which both claim to have been founded in the 13th century by Radu Negru, legendary first Prince of Wallachia.
