The Lea Park Formation is a stratigraphical unit of Late Cretaceous age in the Western Canadian Sedimentary Basin, Canada.
It takes the name from the settlement of Lea Park, Alberta, located north-west of Lloydminster on the banks of the North Saskatchewan River. It was first defined in an outcrop on the river banks, located in section 15-11-54-3W4M by J.A. Allan in 1918.[2] The early campanian age was determined from its foraminifera and mollusks found in the formation.
