Date Hidemune (伊達 秀宗, DAH-tay; November 11, 1591 – July 8, 1658) was a Japanese daimyō of the early Edo period.

Hideyoshi also granted him the court rank of junior 5th, lower grade (従五位下, ju go-i no ge) and the title of ji-jū, appointing the young Hidemune as a page to his own son Toyotomi Hideyori.

Though he was Masamune's eldest son, Hidemune was born by a concubine, and therefore could not be the successor to the Sendai Domain, which his father ruled.

This was made possible in 1614, when father and son took part in the Osaka Campaign: Hidemune received the 100,000 koku Uwajima Domain which Tokugawa Ieyasu granted to Masamune.

Hidemune immediately entered his new fief as daimyō, and ruled until his retirement in Meireki 3 (1657).
