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.

Rizan was, like most officials in the royal government, originally from Kumemura, a Chinese colony and the primary center of learning in the Ryukyu Kingdom.

Having been chosen to start on the track to becoming a bureaucrat, he traveled to China to study at the age of 16, remaining at the Imperial Academy in Beijing for six years.

Ryukyu was invaded in 1609 by forces from the Japanese feudal domain of Satsuma, nominally in response to this and other refusals of Tokugawa Shogunate demands to show gratuity with a courtesy manner.
