Mietje Marie Baron (5 February 1908 – 23 July 1948) was a Dutch swimmer and diver who competed at the 1924 and 1928 Olympics. In 1924 she was sixth in the 4×100 m freestyle relay. She was disqualified in the first round of the 200 m breaststroke event as the judges believed she touched the wall with one hand instead of two hands at one of the turns. Meanwhile her time of 3:22.6 was several seconds ahead of the gold medalist.
