Søren Kjeldsen (born 17 May 1975) is a Danish golfer. He turned professional in 1995.
Kjeldsen's success on the second tier Challenge Tour in 1997, which included victory in the Finnish Open, earned him membership of the main European Tour for 1998. He has performed steadily at this level and won his first European Tour title at the 2003 Diageo Championship at Gleneagles. His second European Tour win came at the 2008 Volvo Masters at Valderrama Golf Club in Andalucia, Spain, where he won by 2 strokes over Martin Kaymer, and Anthony Wall. This was the final staging of the Volvo Masters because as part of the Race to Dubai, introduced in 2009, the European Tour season now concludes at the Dubai World Championship. Kjeldsen won his third European Tour event and second consecutive event on Spanish soil with a three stroke victory over David Drysdale at the 2009 Open de Andalucia in Marbella, Andalusia, Spain.
Kjeldsen represented Denmark in the Eisenhower Trophy in 1994 and at the World Cup in 1998, 1999, 2003 and 2004.
