The Sendai Domain (仙台藩, Sendai-han), also known as the Date Domain (伊達藩, Date-han), was a domain of the Tokugawa Shogunate of Japan during the Edo period from 1600 to 1871.
The Sendai Domain was based at Aoba Castle in Mutsu Province, in the modern city of Sendai, located in the Tōhoku region of the island of Honshu. The Sendai Domain was ruled for its existence by the tozama daimyō of the Date, and under the kokudaka system its income rating at 625,000 koku was the third-largest domain in Japan after the Satsuma Domain and Kaga Domain. The Sendai Domain was geographically the largest domain in northern Japan with its mostly-contiguous holdings covering most of southern Mutsu Province, including all of present-day Miyagi Prefecture, parts of southern Iwate Prefecture and northeastern Fukushima Prefecture. The Sendai Domain was the focal member of the Ōuetsu Reppan Dōmei against the Meiji Restoration during the Boshin War. The Sendai Domain was dissolved in the abolition of the han system in 1871 by the Meiji government.
