Crawford Lake (Wyandot: Kionywarihwaen) is a lake near the community of Campbellville, in the town of Milton, Regional Municipality of Halton, Ontario, Canada. It is located within Crawford Lake Conservation Area, a Regionally Environmentally Sensitive Area, an Ontario Area of Natural and Scientific Interest, and part of the Niagara Escarpment World Biosphere Reserve.
The primary inflow to the lake is an unnamed creek.
Crawford Lake is meromictic, which means it has sequentially deposited seasonal sediment laminations called varves at the bottom; these allow for accurate dating of sediment cores and make Crawford Lake a prime site for archeological and geochemical studies.
