The Kaskapau Formation is a geological formation in North America whose strata date back to the Late Cretaceous. The name derives from kaskapahtew (ᑲᐢᑲᐸᐦᑌᐤ), the Cree word for "smoky". It was first described on the banks of the Smoky River, close to the confluence with the Puskwaskau River by F.H. McLearn in 1926.
