Cleon's Dam was a dam built across the Nile flowing into Lake Moeris in Egypt, connecting the road of the Atef-Pehu Nome to Haueris Nome. It was named for the Greek architect who designed Faiyum's canal system under Ptolemy II Philadelphus. By 48 BC, it had been turned into a Ptolemaic army base, but the medjay Bayek slew Captain Adom Ra-s-hotep-het and rescued the captured rebel leader Uer-mu Ah from the base.
