Tille Höyük is an archaeological site in Southeastern Anatolia, Turkey. It is a small settlement mound on the west bank of the Euphrates some 60 km east of Adıyaman. The site was excavated by the British Institute of Archaeology at Ankara, under the direction of David French, from 1978 to its flooding by the Atatürk Dam in 1990. Surface pottery suggests the site was first occupied in the fourth millennium BC, but large-scale excavation was restricted to the Medieval, Classical and Iron Age levels of the site. A small step-trench recovered Iron Age and Bronze Age pottery in 1980; a more substantial trench was cut into the side of the mound in the last season and reached Late Bronze Age levels.
