{{Nihongo|Date Hidemune|伊達 秀宗||{{Respell|DAH|tay}}; November 11, 1591 – July 8, 1658}} was a Japanese daimyō of the early Edo period.{{Cite book |last=Mass |first=Jeffrey P. |url=https://books.google.com/books?id=Hv99D510nHcC&dq=Date+Hidemune&pg=PA251 |title=The Bakufu in Japanese History |date=1993-08-01 |publisher=Stanford University Press |isbn=978-0-8047-2210-0 |language=en}}{{Cite book |last=Groemer |first=Gerald |url=https://books.google.com/books?id=H6KaDwAAQBAJ&dq=Date+Hidemune&pg=PA45 |title=Portraits of Edo and Early Modern Japan: The Shogun's Capital in Zuihitsu Writings, 1657–1855 |date=2019-05-28 |publisher=Springer |isbn=978-981-13-7376-3 |language=en}} He was the eldest son of Date Masamune, born in 1591 by Shinzo no Kata (a concubine).{{Cite book |last=Roberts |first=Luke S. |url=https://books.google.com/books?id=6F4EEAAAQBAJ&dq=Date+Hidemune&pg=PA114 |title=Performing the Great Peace: Political Space and Open Secrets in Tokugawa Japan |date=2012-02-29 |publisher=University of Hawaii Press |isbn=978-0-8248-6115-5 |language=en}} Coming of age while living with Toyotomi Hideyoshi, he received a character from Hideyoshi's name and took the adult name of Hidemune. Hideyoshi also granted him the court rank of {{Nihongo|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. After Hideyoshi's death in 1598, he was made a hostage at the residence of Ukita Hideie.

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. Masamune therefore considered the possibility of having Hidemune start a branch family. 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).
