The golden swallow ("Tachycineta euchrysea") is a passerine in the swallow family, Hirundinidae.
 Two subspecies are recognised, the Jamaican "T. e. euchrysea" and "T. e. sclateri" of Hispaniola (Haiti and the Dominican Republic).
 It usually inhabits the hills on the interior of islands, preferring open country.
 Currently, this swallow is restricted to isolated montane forests that primarily consist of the Hispaniolan pine.
 This species is considered to be a vulnerable species by the International Union for Conservation of Nature (IUCN), although the nominate subspecies, "T. e. euchrysea", is likely extinct.
 The exact cause of extinction is unknown, but likely factors include predation by mammals and habitat loss, although the habitat loss theory is not supported by very much evidence.
 The last sighting of the nominate subspecies was in Hardwar Gap (located on the boundary between Saint Andrew and Portland parishes), with three birds being seen on 8 June 1989.
