Tamanoumi Daitarō (real name Tomohiro Miura; 2 January 1923 – 27 September 1987) was a sumo wrestler from Ōita, Japan.

Tamanoumi reached his highest rank of sekiwake in 1957 but then was forced to sit out a couple of tournaments through injury.

He fell to the maegashira ranks and considered retiring, but came back to win the top division tournament championship in November 1957 (the first time the Kyūshū honbasho had been staged) with a perfect 15–0 score.

During that tournament he wore a gold-coloured mawashi, the first wrestler to flout the Japan Sumo Association's rule that only dark colours should be worn.
