HMCS Onondaga (S73) is an Oberon-class submarine that served in the Royal Canadian Navy and later the Canadian Forces. Built in the mid-1960s, Onondaga operated primarily with the Maritime Forces Atlantic until her decommissioning in 2000 as the last Canadian Oberon.

Several plans for the disposal of the submarine were made and cancelled before the Site historique maritime de la Pointe-au-Père in Rimouski purchased the boat for preservation as a museum vessel. The submarine was moved into location during 2008, and is open to the public.
