The Gouin dam is a river infrastructure that created the Gouin Reservoir. This dam is the source of the Saint-Maurice River and is located in the town of La Tuque, in Mauricie, in province Quebec, in Canada.

The Gouin dam owes its name to Lomer Gouin (1861-1929), who was premier of Quebec between 1905 and 1920, federal minister of justice between 1921 and 1924 and Lieutenant Governor of Quebec in 1929.

The Kikendatch Bay is formed by the Gouin dam which is located at:

• 4.4 km (2.7 mi) west of the mouth of the Wabano River (confluence with the Saint-Maurice River)
• 71.0 km (44.1 mi) south-east of the center of the village of Obedjiwan which is located on a peninsula on the north shore of Gouin Reservoir
• 55.3 km (34.4 mi) north-west of the center of the village of Wemotaci (north shore of the Saint-Maurice River)
• 142 km (88 mi) north-west of downtown La Tuque
• 252 km (157 mi) northwest of the mouth of the Saint-Maurice river (confluence with the St. Lawrence River at Trois-Rivières).

Completed in 1948, the dam is equipped with a mini-hydroelectric power station fitted with two turbine-generator sets of 300 kW each, in order to meet the needs of the dam itself, of the staff residences of Hydro-Québec assigned to its maintenance and an outfitter located nearby.
