The Rio Balsemão (European Portuguese: [balsˈmɐ̃w] English language: Balsemão River) is a small stream that originates in the mountain range of Serra de Montemuro. It passes through narrow canyons before it reaches the major city Lamego.
Part of the Douro basin, its entire path is made in the old district of Viseu. Born near Rossão, Gosende, in the municipality of Castro Daire, it still draws, for short while, the frontier with neighbors Resende and Lamego before heading on through this last municipality, towards the Douro Valley.
This river has a "Friends of the Balsemão River Association" (Associação de Amigos do Rio Balsemão - ASAMIRB).
