Jana Ueekata Rizan (謝名 親方 利山) (1549–1611), also known by the Chinese-style name Tei Dō (鄭迵) (pinyin Zheng Dong), was a Ryukyuan aristocrat and bureaucrat in the royal government of the Ryukyu Kingdom. A member of the Sanshikan, the king's closest advisors, Rizan was the only Ryukyuan official to refuse to recognize the suzerainty of Japan's Satsuma Domain over the kingdom; he was executed as a result.
