The copper redhorse (Moxostoma hubbsi) is a North American species of freshwater fish in the family Catostomidae. It is found only in Quebec.
Its extremely small range, which is restricted to a few rivers in the lowlands of southwestern Quebec, has contracted significantly in the past few decades. Confirmed populations currently exist in the St. Lawrence, Richelieu rivers and the Rivière des Mille Îles. The copper redhorse is one of seven species of the genus Moxostoma (family Catostomidae) occurring in Canada.
