Lac du Bonnet (French: Lac-du-Bonnet) is a provincial electoral division in the Canadian province of Manitoba. It was created by redistribution in 1957, and has formally existed since the provincial election of 1958. It is a relatively large constituency, located to the northeast of Winnipeg.

Lac du Bonnet is bordered to the west by Red River North and Dawson Trail, to the south by La Verendrye, to the north by Keewatinook and to the east by the Ontario border. Communities in the riding include Lac Du Bonnet, Pinawa, Beausejour (known as the birthplace of Edward Schreyer), Whitemouth, Tyndall, Hadashville, Ste. Rita, and Powerview-Pine Falls.

The riding is currently regarded as a Progressive Conservative/New Democratic Party marginal. The Tories have held the seat since 1988, though they retained it by only a narrow majority in 2003.

The riding's population in 1996 was 20,035. In 1999, the average family income was $45,693, and the unemployment rate was 9.00%. There are a number of diverse economic communities in the riding, including farming, forestry and nuclear research. The service sector accounted for 12% of the riding's industry in 1999, followed by 10% in health and social services.

Lac Du Bonnet is an ethnically diverse riding. Eighteen per cent of the riding's residents are aboriginal, along with 9% German and 6% Ukrainian. Six per cent of the riding's residents are francophone.
