The Kootenai Formation is a Lower Cretaceous geologic formation. The Kootenai was deposited in a foreland basin east of the Sevier thrust belt in western Montana. The lithology consists of a basal conglomerate with overlying non-marine sandstones, shales and lacustrine limestones.[1]

Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.[2]
