Oak Lake is a lake^[1] in the southwestern region of the Canadian province of Manitoba.

Oak Lake is a kettle lake and is an aquifer supplier for numerous nearby residential areas and farms. The lake is in the RM of Sifton and sits at an elevation of 426 metres (1,398 ft) above sea level.^[2] Provincial Road 254 provides access to the lake.

At 39 km² (15 sq mi), Oak Lake is the largest lake in the region and its primary surface inflow is Pipestone Creek, which originates in Saskatchewan. Pipestone Creek enters the lake in the northwest corner through Oak Lake Marsh, which itself is four times the size of Oak Lake.

At the southern end of the lake is Oak Lake Dam (49°38′27″N, 100°45′8″W).^[3][4] While Oak Lake is not a man-made lake, the dam is used to regulate water levels. Water flows past the dam and into the Plum Lakes,^[5] which in turn are drained by Plum Creek and on into the Souris River. The Souris River is part of the Red River drainage basin, which is part of the Hudson Bay drainage basin.

There are no large settlements on the lake. On the north shore is Cherry Point and along the eastern shore is Oak Lake Beach. The community of Oak Lake is about 10 km (6.2 mi) away as the crow flies, or about 16 km (9.9 mi) by car. Brandon, the closest major city, is 70 kilometres (43 mi) away.
