Hiroshi Wajima (Japanese: 輪島大士, Hepburn: Wajima Hiroshi, 11 January 1948 – 8 October 2018) was a Japanese professional sumo wrestler from Nanao, Ishikawa. He was the sport's 54th yokozuna and remains the only wrestler with a collegiate background to reach its highest rank. Entering professional sumo in 1970, he won a total of 14 tournament championships or yūshō during his career before retiring in March 1981. He was later head coach of Hanakago stable, but after several controversies, Wajima was forced to leave the sumo world and turned to professional wrestling.
