The golden-collared toucanet (Selenidera reinwardtii ) is a species of bird in the family Ramphastidae. It is found in the western Amazon rainforest in South America.
The nominate subspecies has a broadly black-tipped maroon-red bill, while S. r. langsdorffii has a broadly black-tipped bluish-grey bill. The plumage of both subspecies is very similar to that of the related spot-billed, tawny-tufted and Gould's toucanets. It is 30.5–35 cm (12–14 in) long and weighs from 129 to 200 grams (4.5-7.1 oz.)
