Miss Waldron's red colobus (Piliocolobus waldronae) is a species of the red colobus native to West Africa. It had previously been described as a subspecies of the western red colobus, P. badius. It has not been officially sighted since 1978 and was considered extinct in 2000. However, new evidence suggests that a very small number of these monkeys may be living in the southeast corner of Côte d'Ivoire. The IUCN Red List notes Miss Waldron's red colobus as critically endangered.
Miss Waldron's red colobus was discovered in December 1933 by Willoughby P. Lowe, a British Museum (Natural History) collector who had shot eight specimens of the animal. Robert William Hayman named it after a fellow museum employee, Miss Fanny Waldron, who assisted in the expedition where Lowe collected the eight specimens.
