The Tapanahony River (sometimes called Tapanahoni) is a major river in the south eastern part of Suriname, South America. The river originates in the Southern part of the Eilerts de Haan Mountains, near the border with Brazil. It joins the Marowijne River at a place called Stoelmanseiland. Upstream, there are many villages inhabited by Indian Tiriyó people, while further downstream villages are inhabited by the Amerindian Wayana and Maroon Ndyuka people.
