Lago dell'Antenna is an artificial lake in north-west Italy, located in the Genoa (Liguria).

[2] The lake was created by blocking the Orba with a dam about two kilometres upstream of San Pietro d'Urbe, in order to produce electricity.

The lake is located on the northern border of Parco naturale regionale del Beigua, which encompasses its left shore.

Antenna lake was realised in 1922 in order to provide water to the hydroelectric power plant of the Cotonificio Ligure, located in San Pietro d'Orba.

The lake is also defined as touristic fishing reserve (riserva di pesca turistica), and is restocked with rainbow trouts when authorised by Parco del Beigua.
