Date Masamune (伊達 政宗, September 5, 1567 – June 27, 1636) was a Japanese daimyo in the Tōhoku region during the Azuchi-Momoyama period and Edo period. He was known as the "one-eyed dragon" (独眼竜, dokuganryū) because he lost the use of an eye.

In the Edo period, the Date clan were identified as one of the tozama or outsider clans, in contrast with the fudai or insider daimyō clans which were hereditary vassals or allies of the Tokugawa clan.
The feudal daimyō were sometimes identified with the suffix "-kō" (servant) combined with the name of a place or a castle.
