The Wordie Creek Formation is an uppermost Permian and Lower Triassic geologic formation in Greenland, outcrops of which are located in Northeast Greenland National Park (until 2008 Tunu County, Danish: Østgrønland, English: East Greenland). In 2017, it was suggested to be raised to group status, as the Wordie Creek Group.
The Lower Triassic sediments in the region were discovered in 1926 independently by James Wordie and Lauge Koch, and the latter named the formation. The rock layers preserve fossils of invertebrates (e.g., ammonoids, gastropods), fishes (coelacanths, ray-finned fish, cartilaginous fish) and temnospondyl amphibians, dating back to the Induan age.
