Baron Date Muneatsu (伊達 宗敦, DAH-tay; 20 June 1852 – 6 January 1911) was a Bakumatsu period Japanese samurai, and the second Imperial Governor of former Sendai Domain in the Tōhoku region of northern Japan.

At that time, he was given the Court rank of Junior Fourth, Lower Grade and courtesy titles of Sakon Daiyu and Jijū.

Later that year, Sendai Domain and the Ōuetsu Reppan Dōmei were defeated in the Boshin War of the Meiji Restoration, and Yoshikuni resigned his offices and went into voluntary retirement and seclusion in Tokyo.

The new Meiji government ordered that his fourth son, the two-year-old Date Munemoto become daimyō of a much reduced Sendai Domain.

In 1884, he set up his own household separate from the main Date clan, and on May 11, 1889 was granted the title of danshaku (baron) in the new kazoku peerage system.
