Mesopithecus ("middle monkey") is an extinct genus of Old World monkey that lived in Europe and western Asia 7 to 5 million years ago. It was once thought that it might be an ancestor of the grey langur, but a more recent study suggests that they are more closely related to the snub-nosed monkeys and doucs.
