Tow Hill is a large isolated volcanic plug located east of Masset on the north end of the Naikoon Peninsula of northeast Graham Island in Haida Gwaii, British Columbia, Canada, east of McIntyre Bay and near the mouth of the Hiellen River, which is the site of Hiellen, a now-abandoned Haida village and of the Hiellen Indian Reserve No. 2, on the site of that village. Formerly Tow Hill Provincial Park, it is now part of Naikoon Provincial Park, which covers most of the northeastern flatland of Graham Island.
