Hiodoshi Katsugorō (Japanese: 緋縅 勝五郎, born Moriwaki (森脇), 1773 – February 22, 1830) was a Japanese sumo wrestler from Yamagata District, Aki Province (now Kitahiroshima, Hiroshima Prefecture).

He began his career in the Osaka-based sumo association under the patronage of the Awa-Katsuyama Domain but joined the Edo-based association in 1794 and began his career directly in the sandanme division under the shikona, or ring name, Hiodoshi Rikiya (緋縅 力彌).

At the time of his repromotion to san'yaku he changed his shikona to Hiodoshi Katsugorō (緋縅 勝五郎).

He retired in January 1822, concluding a career of rare longevity (even by today's standards) of 28 years, including 21 in the top division.
