Mequinenza Dam (Spanish: Presa de Mequinenza) is a concrete gravity dam in the province of Zaragoza, Spain. It impounds the Ebro creating a large reservoir, which is called Mar de Aragón.^[1] About 35 km downstream of Mequinenza dam is Ribarroja dam.

Empresa Nacional Hidroeléctrica del Ribagorzana S.A. (ENHER) was mandated in 1955^[2]^[3] by Instituto Nacional de Industria (INI) to build two dams on the Ebro near Mequinenza and Ribarroja. Work on Mequinenza dam started in 1957.^[1] The filling of the reservoir began in December 1965.^[2] The power plant was operational in 1964^[3]^[4] (1966^[5]). ENHER was acquired by Endesa in 1999.^[6]
