Lac la Nonne is a lake in northern Alberta, Canada. It is located between Lac Ste. Anne County and the County of Barrhead No. 11, 85 km north-west from Edmonton, east of the Grizzly Trail.
The lake is located within the Athabasca River basin and is fed by Majeau Creek, with water levels controlled by a dam, on the outflowing MacDonald Creek which then flows into the Pembina River.
