Hōō Umagorō (鳳凰 馬五郎, September 3, 1866 – May 4, 1907) was a Japanese professional sumo wrestler from Narashino, Shimōsa.

His years as a top division wrestler were marked by his strong rivalry with Yokozuna Konishiki and then-sekiwake Asashio.

[2] However, due to heavy drinking problems,[3] Hōō was denied the rank after the May, 1898 tournament and dropped back to maegashira in 1902.

[1] After his retirement, he was a popular master who was well received by younger generations, among whom he recruited future yokozuna Ōtori, to whom he bestowed his old shikona.
