The Rein da Tuma is a river in Switzerland, in the Canton of Graubünden. It rises east of the Rossbodenstock with two or three mountain streams, that flow across the Tuma Alp into the Lake Toma (German: Tomasee, Romansh: Lai da Tuma). Before they reach the lake, they flow through a plane and form small meanders. The Rein da Tuma flows out of Lake Toma on the north east and flows as Anterior Rhine past the village of Tschamut in the municipality of Tujetsch.
