Quebecius is an extinct genus of porolepiform sarcopterygian fish which lived during the Late Devonian period of Quebec, Canada.
[1] It is related to Glyptolepis, although distinguished from the latter by an especially broad pelvic fin base: uniquely among lobe-finned fish, only the pectoral fins are lobed.
Specimens have been found to measure between 5 and 60 centimeters long.
