Cumberland Lake (formally Pine Island Lake) is a glacial lake in the Canadian province of Saskatchewan. It is situated in the Saskatchewan River Delta in east-central Saskatchewan, about 60 kilometres (37 mi) from the Manitoba border. Cumberland House and Cumberland House Provincial Historic Park are on the south shore of the lake on Cumberland Island. Access to the lake and its amenities is from Highway 123 and Cumberland House Airport.
The area around Cumberland Lake has been inhabited by humans for over 7,000 years, is the site of the oldest permanent settlement in Saskatchewan, and was the interior hub for three canoe routes travelled by Voyageurs during the fur trade era. Lake (and delta) water levels have been dropping in recent years due to upstream damming, water usage, and water diversion.
