Wilusa (Hittite: URUWi-lu-ša) <English pronunciation: wi-lu-sha> was a city of the late Bronze Age Assuwa confederation of western Anatolia.
It is known from six references in 13th century BC Hittite sources, including:
It is often identified with Troy VIIa in archaeology (destroyed in ca. 1190 BC), and with legendary Troy of the Greek Trojan War cycle (according to the chronology of Saint Jerome, dated to the 1180s BC). In terms of etymology, Ilios/Ilion (Ἴλιος, Ἴλιον), a Greek name for Troy, is identified with Wilusa. Not all scholars agree on this. There is a hypothesis that Wilusa was in the place of the Byzantine town "Ilusa" (Ιλούζα), in what is today Beycesultan.
