Date Munekatsu (伊達宗勝, DAH-tay; 1621 – December 6, 1679) was a Japanese daimyō of Ichinoseki Domain in early-Edo period Japan.
Sendai Domain was inherited by the young and impressionable Date Tsunamune, and the clan elders appointed Munekatsu and his half-brother, Tamura Muneyoshi as guardians.
Through these connections, the Munekatsu and Tamura Muneyoshi accused Tsunamune of drunkenness and debauchery, who then removed from office for misrule and was confined to a secondary clan residence in Edo.
Ten years of violence and conflict followed in Sendai Domain, reaching a climax in 1671 when Aki Muneshige, a powerful relative of the Date clan, complained to the shogunate of the mismanagement of the fief under Tsunamura and his uncles.
In the ensuring Date Sōdō, Munekatsu was relieved of his offices in 1671 and the branch of his family was dissolved.
