Jackfish Lake is a large body of shallow water in central Saskatchewan, Canada. It is located about 48 kilometres (30 mi) south of the village of Edam on Highway 26. Communities on or near the lake shore include Meota, Metinota, Cochin, and Aquadeo. The lake is accessed from Highways 4, 26, 697, 674, 769, and 204.

Jackfish River, located at the lake's southern end, is the primary outflow. It exits the lake at the southern end and flows south into the North Saskatchewan River. Charette Creek, Jackfish Creek, and a short stream from Murry Lake at Cochin are the primary inflows.

The lake is surrounded by several beaches, with three campgrounds, over 300 campsites and several hiking trails at The Battlefords Provincial Park. Meota Regional Park is located at the southern end of the lake beside the village of Meota.

Fish commonly found in the lake include perch, walleye, pike, burbot, and whitefish.
