Ginji Miyauchi (died 2019) was a Japanese yakuza boss who was patriarch of the Miyauchi-gumi subsidiary of the Omi Alliance during the 2010s. In 2019, he and the other Omi patriarchs rebelled against Chairman Masaru Watase when he announced the Omi's dissolution, but Kazuma Kiryu slashed him and several other patriarchs to death with their own swords and daggers.
