Ōtomo Sōrin (大友 宗麟?, January 31, 1530 – June 11, 1587), also known as Fujiwara no Yoshishige (藤原 義鎮) and Ōtomo Yoshishige (大友 義鎮), was a Japanese feudal lord (daimyo) of the Ōtomo clan, one of the few to have converted to Christianity. The eldest son of Ōtomo Yoshiaki, he inherited the domain of Funai, on Kyūshū, Japan's southernmost main island, from his father. He is perhaps most significant for having appealed to Toyotomi Hideyoshi to intervene in Kyūshū against the Shimazu clan, thus spurring Hideyoshi's Kyūshū Campaign of 1587.
