Tendō Domain was a feudal domain in Edo period Japan, located in Dewa Province, Japan. It was centered in what is now the city of Tendō, Yamagata. Tendō was ruled by the tozama Oda clan, direct descendants of the famed Oda Nobunaga, throughout its history. Although styled with the honorific of "castle", the clan residence was in fact a jin'ya, or fortified house.
