Lago di Livigno or Lago del Gallo is a reservoir in the Livigno valley. The reservoir is mostly in Italy whereas the Punt dal Gall arch dam is crossed by the border with Switzerland (Zernez , Grisons ).

The reservoir's surface area is 4.71 km².

The reservoir has a capacity of 164 million m³. Its minimum and maximum water levels above sea level are at 1,700 metres and 1,805 metres respectively. Since its construction, this reservoir had been off-limits for any activity, such as wind-surfing or rowing, until the summer of 2005, when Italy's National Rowing team was authorized to train on the lake.
