The Canelles reservoir (in Catalan: Embassament de Canelles) is located in the Spanish provinces of Huesca and Lleida, along the course of the Noguera Ribagorzana river. It has a capacity of 688 hm³ and is mainly used for electricity generation.
It was built by the former public company Enher (now Endesa) in 1960. Due to its capacity, it is the largest reservoir in the Noguera Ribagorzana basin and the second largest in the Ebro basin after the Mequinenza Reservoir.
