The Manitoba Group is a stratigraphical unit of middle to late Devonian age in the Western Canadian Sedimentary Basin.

The group takes its name from the province of Manitoba, and was first defined by A.D. Baillie in 1953.

[2] The Manitoba Group is composed of alternating cycles of shale, carbonate and evaporite.

The following formationas are recognised, from top to bottom: The Manitoba Group is conformably overlain by the Duperow Formation and disconformably overlays the Prairie Evaporite Formation or Winnipegosis Formation of the Elk Point Group.

[1] The lower Manitoba Group is equivalent to the Muskeg Formation in northern Alberta, while the upper part correlates with the Beaverhill Lake Formation.
