Klaas-Erik Zwering (born 19 May 1981 in Eindhoven, North Brabant) is a former Dutch swimmer and an Olympic medalist. He is currently studying MBO entrepreneurship as he trained in Eindhoven with the PSV Eindhoven swim club. His personal coach was Jacco Verhaeren, who is also coach for Dutch swimming phenom Pieter van den Hoogenband.
Zwering originally specialized in the 200 meter backstroke, coming in seventh place in his first senior competition at the European Championships in Istanbul. In the 2000 Olympic Games in Sydney, he came in tenth place in the same event. Recently, however, he's been focusing exclusively on freestyle swimming.
