Lech dl Dragon (Drachensee in German) is a proglacial lake in the Dolomites of South Tyrol, Italy.

The lake is located on a ledge on the north side of the Sella Group.

It is created periodically from the melting of a glacier that is hidden beneath the scree from the rock towers, above.

The lake is named from a legend of the inhabitants of Val Gardena.

The legend describes the screams of a dragon living in the area.
