The Réunion Pink Pigeon is an extinct species of pigeon that formerly lived on the Mascarene island of Réunion. It is known from the description of a rusty-red pigeon given by Dubois in 1674 and a single subfossil humerus that agrees with that of the Pink Pigeon of Mauritius in generic characteristics, except being slightly longer. Also, Dubois' reference to the bill being red at the base and the eyes being surrounded by a red ring suggest that this species was closely allied to the Mauritus taxon.
The Columba duboisi is classified as Extinct (EX), there is no reasonable doubt that the last individual has died.
