The Devon Island Formation is a geologic formation in the Canadian Arctic. [1] It preserves fossils dating back to the late Silurian and Devonian periods. [2]

The formation was originally named by Raymond Thorsteinsson for a sequence of calcareous, graptolitic mudrocks on northern Devon Island situated between the Douro Formation below and the Sutherland River Formation above. [1] The latter formation is now considered synonymous with the Goose Fiord Formation. [2] The Devon Island Formation extends from the west coast of Devon Island through the Grinnell Peninsula, and well across the southern part of Ellesmere Island. [2]
