The Junin crake or Junin rail (Laterallus tuerosi) is a species of bird in the family Rallidae. It has sometimes considered a distinctive subspecies of the black rail (L. jamaicensis).The Junín rail is, as suggested by its common name, endemic to marshy habitats around Lake Junín in west-central Peru. It is threatened by habitat loss. The Junin flightless grebe, another highly endangered species, is restricted to the same lake.
