Erythrocebus is a genus of Old World monkey. All three species in this genus are found in Africa, and are known as patas monkeys.^[2][3] While previously considered a monotypic genus containing just E. patas, a 2017 review argued that, based on morphological evidence and heavy geographic separation between taxa, E. patas should be split back into distinct species as recognised in the 19th century.^[4]

There are three species recognized.^[4][5][6]
