Tendō Domain (天童藩, Tendō-han) was a feudal domain in Edo period Japan, located in Dewa Province (modern-day Yamagata Prefecture), 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.
