Rena Kanokogi (née Glickman; July 30, 1935 – November 21, 2009) was a renowned judo expert. In 1959, disguised as a man, she won a medal at a YMCA judo tournament, but had to return it after acknowledging that she was a woman. Traveling to Japan to continue her judo training, Kanokogi became the first woman allowed to train in the men’s group at the Kodokan. She is perhaps best known for pioneering women’s judo competition at the Olympic Games.
