Date Tsunamune (伊達 綱宗, 23 September 1640 – 19 July 1711) was an early Edo period Japanese samurai, and the 3rd daimyō of Sendai Domain in northern Japan from 1658 to 1660, and the 19th hereditary chieftain of the Date clan. Tsunamune's succession and rule was soon opposed by a number of his kinsmen and vassals. This dispute eventually led to the Date Sōdō or "Date Disturbance" of 1671, which has been retold in theatre, and has become one of the more well-known tales of unrest and disunity among the daimyō of the Edo period.
