The Jamaican blackbird (Nesopsar nigerrimus) is a species of bird in the New World blackbird and oriole family Icteridae. It is the only species (monotypic) in the genus Nesopsar. The species has sometimes been included in the genus Agelaius, but molecular systematics have shown it not be closely related to any living New World blackbird or grackle. The species is endemic to Jamaica, where it is restricted to Cockpit Country, some central areas and the Blue and John Crow Mountains.
