The Réunion parakeet (Psittacula eques eques) was a little-known parakeet, extinct from about 1770, which formerly inhabited Réunion Island in the western Indian Ocean. It was similar to the echo parakeet of Mauritius. The two may either be distinct subspecies of the same species or the same taxon.
