The Lérez is a river in South West Galicia, Spain. The river meets the Atlantic Ocean at Pontevedra, where it creates Pontevedra's ria. The sources of the 60-kilometre (37 mi) long stream are in Serra do Candán, in the mountain of San Bieito, in the parish of Aciveiro (Forcarei). The Lérez passes through the communities of Forcarei, Cerdedo, Campo Lameiro, Cotobade and, finally, Pontevedra.

Its main tributaries are the Salgueiro, Cabaleiros, Grande, O Castro, Quireza, Tenorio and Almofrei.
