The Ntako River (IPA: /ɪnˈtaːkəʊ/) is a major river of north-eastern Epiros. Its source is Lake Mamagamimeno in Dierminevin. It forms Dierminevin's border with Angouri Forest and part of the border with Anvero. It then acts as the border between Anvero and Elsavet before discharging into the Thalas Sea at Epipida Bay.
