Ouranopithecus macedoniensis is a prehistoric species of Ouranopithecus from the Late Miocene of Greece. This species is known from three localities in Northern Greece. The type location is Ravin de la Pluie. The other localities are Chalkidiki and Xirochori. It is known from a large collection of cranial fossils and few post cranial. The material has been dated to the late Miocene 9.6 – 8.7 million years old, so slightly earlier than O. turkae. To some this suggests O. turkae is the direct ancestor to O. macedoniensis although it is generally accepted that they are sister taxons.
