The Smoky Group is a stratigraphical unit of Late Cretaceous age in the Western Canadian Sedimentary Basin.

[2] The Smoky Group is represented by marine silty shale with ironstone and bentonite streaks.

Sandstone occurs at the base and is transitional to the Dunvegan Formation.

The entire group measures up to 677 m (2,220 ft) in the Pouce Coupe Prairie and can reach 1,100 m (3,610 ft) in the Canadian Rockies foothills of northeast British Columbia.

The Cardium sandstone and Muskiki shale are replacing the upper parts of the Kaskapau Formation in the south-east of the distribution area.
