The sunset lorikeet (Trichoglossus forsteni), also known as the scarlet-breasted lorikeet or Forsten's lorikeet, is a species of parrot that is endemic to the Indonesian islands of Bali, Lombok, Sumbawa, Tanahjampea (between Sulawesi and Flores), and Kalaotoa (between Sulawesi and Flores). It was previously considered a subspecies of the rainbow lorikeet, but following a review in 1997, it is increasingly treated as a separate species.
