Kazuhiro Mizoguchi (溝口 和洋, Mizoguchi Kazuhiro; born March 18, 1962) is a Japanese former javelin thrower. He set the world best year performance in 1989, throwing 87.60 metres at a meet in San Jose, California, United States on May 27, 1989. Initially, it was announced as a new world record of 87.86m, 20cm further than the previous world record, but the measurer re-measured it with a plastic tape measure and announced it as 87.60m.
