The Hawaiian Duck (Anas wyvilliana) is a species of bird in the family Anatidae. It is endemic to the large islands of Hawaiʻi. Some authorities treat it as an island subspecies of the Mallard, based on their capacity to produce fertile hybrids, but it appears well distinct and capability of hybridization is meaningless in dabbling duck taxonomy. The native Hawaiian name for this duck is koloa maoli.
