The '''Belly River Group''' is a [[Stratigraphy|stratigraphical]] unit of [[Late Cretaceous]] [[Geochronology|age]] in the [[Western Canadian Sedimentary Basin]].
 
It takes the name from the [[Belly River]], a tributary of the [[Oldman River]] in [[southern Alberta]], and was first described in outcrop on the banks of the [[Oldman River]] (at the time considered part of the Belly River) and [[Bow River]] by [[George Mercer Dawson]] in 1883.<ref>Dawson, G.M., 1883. Preliminary report on the geology of the Bow and Belly river region, Northwest Territory, with special reference to the coal deposits.
