The Labrador duck (Camptorhynchus labradorius) was a North American bird; it has the distinction of being the first known endemic North American bird species to become extinct after the Columbian Exchange, with the last known sighting occurring in 1878 in Elmira, New York. It was already a rare duck before European settlers arrived, and as a result of its rarity, information on the Labrador duck is not abundant, although some, such as its habitat, characteristics, dietary habits and reasons behind its extinction, are known. There are 55 specimens of the Labrador duck preserved in museum collections worldwide.
The Labrador duck had an oblong head with small, beady eyes. Its bill was almost as long as its head. The body was short and depressed with short, strong feet that were far behind the body. The feathers were small and the tail was short and rounded. The Labrador duck belongs to a monotypic genus
