Oak Lake is an unincorporated urban community in the Rural Municipality of Sifton within the Canadian province of Manitoba that held town status prior to January 1, 2015.

During the late 19th century, the area around Oak Lake was a popular stopping point for fur traders and settlers due to the large number of big oak trees (revered for their strength) located around the lake that could be used to repair their wagons.

In the fall of 1881, work crews on the transcontinental Canadian Pacific Railway had reached Flat Creek to the east of the current townsite.

In the spring they moved the camp west and built a siding and station (now long gone) where the community's flags and flower garden are now located.

There is often much snowfall during the winter, with the possibility for blizzards that can drop in excess of 35 cm (~14 inches) of snow at once, which can be blown into drifts that are much deeper.

The rural municipality office is located in Oak Lake, which employs a handful of people to manage the running of public services.

Other employers include the Valleyview CO-OP grocery store, Golden Embers restaurant, Dandy's confectionery, and several smaller, personal businesses.

For people who live and work in community, walking or biking is common when the weather permits.
