The Blue Nile patas monkey (Erythrocebus poliophaeus ) or Heuglin's patas monkey is a species of Old World monkey found in Africa along the Blue Nile river valley in Ethiopia, Sudan, and potentially South Sudan. While first described in 1862, it was synonymized with the common patas monkey (E. patas ) in 1927. A 2017 study reclassified it as a distinct species.

Not a migrantAnimals that do not make seasonal movements and stay in their native home ranges all year round are called not migrants or residents.

starts withThis species has white hairs on upper lip hair which forms the shape of a handlebar moustache. This, when combined with the lack of the band between the ear and eye found in other members of Erythrocebus, distinguishes it from the rest of the genus.
This species is thought to be restricted to the area between the Nile and the western escarpment of the Great Rift Valley. It ranges from the vicinity of Metemma south to the Sudd. Although it is only known from Ethiopia and Sudan, it could potentially occur in South Sudan.
In prehistoric times, this species may have had its range restricted to a montane refugium in western Ethiopia, through which it survived a period of aridification.
Little historical data and few museum voucher specimens exist of this species from Ethiopia, indicating that it was likely never common there. Although no specific threats are known, this species is likely at threat from human activities in its range. The villagization program in the 1980s saw large amounts of people being forcibly relocated into planned villages, including those built in the restricted range of E. poliophaeus. The subsequent residential development and agricultural expansion in its habitat may leave the species at heavy risk. The illegal wildlife trade in live animals also threatens this species and has been shown to lead to rapid population declines. However, as its geographic range is poorly known, it is classified as Data Deficient.
