Maria Petronella "Puck" Oversloot (22 May 1914 – 7 January 2009) was a Dutch swimmer. Together with Marie Braun, she was the top national backstroke and freestyle competitor. At the 1932 Summer Olympics, Braun was listed for the 4 × 100 m freestyle relay, but fell ill and was replaced by Oversloot. The team won a silver medal, setting a new European record. Both Braun and Oversloot qualified for 400 m freestyle semifinals, but because Braun could not participate, Oversloot withdrew from the event, in solidarity. In 1933, Oversloot broke the national record in 100 m backstroke set by Braun and became the national champion. She won a bronze medal in the same event at the 1934 European Aquatics Championships. She was born and died in Rotterdam.
