Rin Seikō (林 世功?, 1842–1880) was a scholar-bureaucrat and diplomat of the Ryūkyū Kingdom. He was known for leading a movement to petition the government of Qing Dynasty China to rescue the Ryūkyū Kingdom from annexation by Imperial Japan.
It was standard at the time for members of Ryūkyū's aristocratic class to have two names: Chinese style name (唐名 Karana?) and Japanese style name (大和名 Yamatona?). "Rin Seikō" was his Chinese style name, while "Nashi Shunbō" (名城 春傍?) or "Nashi Rosatonushioyakumoi Shunbō" (名城 里之子親雲上 春傍?) was his Japanese style name.
