Karen Venhuizen (born 4 April 1984) is a Dutch former competitive figure skater.

In March, she competed at the 2000 World Junior Championships in Oberstdorf; she advanced out of her qualifying group but was eliminated after the short program.

Venhuizen made her final junior-level appearances at the start of the 2000–01 season before repeating as the Dutch national senior champion.

Venhuizen won gold medals at the 2003 Triglav Trophy in Slovenia and at the 2007 International Challenge Cup in The Hague.

It was also the highest placement by a Dutch figure skater since Dianne de Leeuw became the European champion in 1976.
