Ōikari Montarō (大碇 紋太郎; February 22, 1869 – January 27, 1930) was a Japanese professional sumo wrestler from Chita District, Owari Province (now Handa, Aichi Prefecture). Wrestling for the Tokyo-based Sumo Association, he made his debut in May 1885 at Isenoumi stable. He reached the makuuchi division in January 1893 and reached the rank of ōzeki in 1895. Because he later wrestled for the Kyoto-based Sumo Association, he was awarded a yokozuna license by the Gōjō family in April 1899. However, since this yokozuna license was not issued by the Yoshida family, he is not recognized by the Japan Sumo Association as being on the list of official yokozuna. Although he retired from the Tokyo Sumo Association in 1898, his final retirement date is unknown.
