Lago Ritom is a lake in the Piora valley, Ticino, Switzerland. The natural lake is used as a reservoir by the Swiss Federal Railways (SBB-CFF-FFS) to generate hydro-electric power for the Gotthard line. The first dam was built in 1918 and, in 1950, its height was increased by 23 m.


The lake's surface area is 1.49 km² at an elevation of 1850 m. With Lake Cadagno and Lago di Tom, it is one of the main lakes in the Piora valley.

Before being used as a reservoir, Lake Ritom was a meromictic lake similar to the nearby Lake Cadagno.
