Maria "Rie" van Veen (also Ria, Rietje) (11 February 1923 – 1995) was a Dutch swimmer who won three medals at the 1938 European Aquatics Championships. Earlier on 26 February 1938 she set a new world record in the 200 m freestyle. Between 1938 and 1942 she won all national titles in the 100 m and 400 m freestyle events; she also won the 100 m in 1937. She married Adrianus "Arie" Thuis, a swimming coach from Haarlem, on 27 May 1943 and retired shortly thereafter.
