Quebecoceras is an extinct genus from the nautiloid order Ellesmerocerida that lived during the Gasconadian Stage at the beginning of the Early Ordovician.

Quebecoceras is a cyrtoconic, similar to Dakeoceras and Paradakeoceras except for having a circular cross section and more persistent curvature and rate of expansion. Paradakeoceras differs in having a somewhat flattened venter.

The only known species, Quebecoceras quebecense, is half again a large as the largest known Dakeoceras, making it a fairly large ellesmeroceratid genus.
