Sunpu Domain (駿府藩 Sunpu-han?) was a feudal domain under the Tokugawa shogunate of Edo period Japan. The domain centered at Sunpu Castle what is now the Aoi-ku, Shizuoka. From 1869 it was briefly called Shizuoka Domain (静岡藩?).
During the Muromachi period, Sunpu was the capital of the Imagawa clan. The Imagawa were defeated at the Battle of Okehazama, and Sunpu was subsequently ruled by Takeda Shingen, followed by Tokugawa Ieyasu. However, Toyotomi Hideyoshi relocated Ieyasu from his territories in the Tōkai region of Japan, and installed Nakamura Kazutada in his place. After the Toyotomi were defeated in the Battle of Sekigahara, Ieyasu recovered Sunpu and relocated Nakamura to Yonago in Hōki Province. Sunpu was initially reassigned to Naitō Nobunari in 1601. This marked the start of Sunpu Domain.
In April 1606, Ieyasu officially retired from the post of Shogun, and he retired to Sunpu, where he established a secondary court, from which he could influence Shogun Tokugawa Hidetada from behind the scenes. Naitō was transferred to Nagahama in Ōmi Province.
