The Hidden Lake Formation is a Late Cretaceous geologic formation in Antarctica. The sandstones and siltstones of the formation were deposited in a deltaic environment.

Indeterminate megalosaur remains have been recovered from it.^[2] Also many plant fossils and ichnofossils of Planolites sp. and Palaeophycus sp. have been found in the formation.^[3]
