Sunpu jōdai (駿府城代) were officials of the Tokugawa shogunate with responsibility for holding and defending Sunpu Castle (Sunpu-jō), also called Shizuoka Castle.
Appointments to the prominent office of castle warden at Shizuoka were exclusively fudai daimyō. Conventional interpretations have construed this Japanese titles as "commissioner" or "overseer" or "governor."
