Last Mountain Lake, also known as Long Lake, is a prairie lake formed from glaciation 11,000 years ago. It is located in south central Saskatchewan, Canada, about 40 kilometres (25 mi) north-west of the city of Regina. It flows into the Qu'Appelle River via Last Mountain Creek, which flows past Craven. It is approximately 93 km (58 mi) long, and 3 km (1.9 mi) across at its widest point. It is the largest naturally occurring body of water in southern Saskatchewan. Only Lake Diefenbaker, which is man-made, is larger. The lake is a popular resort area for residents of south-eastern Saskatchewan.
