Amūru Mitsuhiro (阿夢露 光大, born August 25, 1983 as Nikolai Yuryevich Ivanov) is a former professional sumo wrestler from Lesozavodsk, Primorsky Krai, Russia. After an initial influx of Russian wrestlers from the early 2000s, he was the last ethnic Russian in top level sumo. He made his debut in May 2002 and, after a serious knee injury in 2012 sent him down the rankings, reached the top makuuchi division in November 2014. His highest rank was maegashira 5. He had nine tournaments ranked in the top division, but finished his career in the third highest makushita division.
