Lago di Toblino (Tobliner See in German) is a lake in Trentino, Italy.

The basin is declared — together with the surrounding area — a biotope for both botanical and ethological interests, and is protected by the Autonomous Province of Trento.

It occupies the terminal part of the Valle dei Laghi, not far from Trento and the inhabited areas of Padergnone, Sarche, Vezzano and Calavino.

On a promontory located on the northern coast of the lake, stands a castle of medieval origin, called Castel Toblino.
