was a king of the Ryukyu Kingdom, the second ruler of the second Shō dynasty. He ruled for only six months after his elder brother Shō En died, and was forced to abdicate to his nephew, Shō Shin.
Shō Sen'i was named Prince of Goeku (越来王子) after his abdication, and given Goeku magiri (today part of Okinawa City) as his domain, but died in the same year. It has been suggested that he was murdered by the queen dowager Ukiyaka.
