The Duchers ( or дучеры) was the Russian name of the people populating the shores of the middle course of the Amur River, approximately from the mouth of the Zeya down to the mouth of the Ussuri, and possibly even somewhat further downstream. Their ethnic identity is not known with certainty, but it is usually assumed that they were a Tungusic people, related to the Jurchens and/or the Nanais.
