Chatan Wōji Chōki (北谷 王子 朝騎, 16 September 1703 – 27 March 1739), also known by his Chinese style name Shō Tetsu (尚 徹), was a prince of the Ryukyu Kingdom. Chatan Chōki was the second son of King Shō Eki, and was also a younger brother of King Shō Kei. He became the adopted son of Chatan Chōai because Chōai had no heir. After Chōai died in 1719, he became the second head of a royal family called (大村御殿). Chōki served as sessei from 1722 to 1739. During his term, he supported Sai On's reform, and signed many laws. Like his adopted father, he died without an heir.
