Conca de Dalt is a municipality in the comarca of the Pallars Jussà in Catalonia, Spain. The municipal territory extends to both the east and west of la Pobla de Segur, on the sides of the valley of the Noguera Pallaresa river. The municipality was known as Pallars Jussà from its formation in 1969 (by the fusion of twelve smaller municipalities) until 1995, when the name was changed to avoid confusion with the comarca.
