The red-collared lorikeet (Trichoglossus rubritorquis) is a species of parrot found in wooded habitats in northern Australia (north-eastern Western Australia, northern Northern Territory and far north-western Queensland). It was previously considered a subspecies of the rainbow lorikeet, but today most major authorities consider them as separate species. No other member of the rainbow lorikeet group has an orange-red collar over the nape.
The red-collared lorikeet measures around 26 centimetres long. The feathers of the head and throat are dark brown with blue shafts. There is an orange-red band on the back of the neck. The chest is orange with red. The base of the hindneck is dark blue. The wings are green. The bill is red. The legs and feet are grey-brown. The sexes are similar in plumage while the juvenile has duller plumage and a dark bill.
The red-collared lorikeet is distinguished from the rainbow lorikeet by the latter's green rather than red nape, the lack of a blue mantle and more yellow-green underparts. The two may both occur where their ranges abut east of the Gulf of Carpentaria.
