Ōuchi Hiroyuki

Ōuchi Hiroyuki (c. 1305–1352) was the eighth head of the Ōuchi clan of Suō Province in the late Kamakura period. He inherited in 1320 and marched to Kyoto on Hōjō Takatoki's orders in the Genkō War of 1332, after which the Kenmu regime gave the clan's Suō shugo post to his uncle Washizu Nagahiro.

Hiroyuki joined Ashikaga Takauji in 1335 and in 1350 marched against Nagahiro with his son Hiroyo. He submitted to the Southern Court in 1351, when Hiroyo was made Suō shugo, and died in 1352 with the feud unresolved.
