The Mascarene parrot or Mascarin (Mascarinus mascarin) is an extinct species of parrot that was endemic to the Mascarene island of Réunion in the western Indian Ocean. The taxonomic relationships of this species has been subject to debate. It has been connected to the Psittaculini parrots based on anatomical grounds, but to the vasa parrots based on genetic grounds. The exact placement is unresolved.

The Mascarene parrot was 35 cm (14 in) in length with a large red bill and long, rounded tail feathers. Its legs were red, and it had naked red skin around the eyes and nostrils. It had a black facial mask and partially white tail feathers, but the colouration of the body, wings and head is unclear. Descriptions from life indicate the body and head were ash grey, and the white part of the tail had two dark central feathers. In contrast, descriptions based on stuffed specimens state that the body was brown and the head bluish but do not mention the dark central tail feathers. This may be due to the specimens having changed color as a result of aging and exposure to light, as well as other forms of damage. Very little is known about the bird in life.
