Jan Kromkamp is a Dutch former footballer who played as a right back.
Kromkamp played a total of 201 games in the Eredivisie and scored eight goals in nine seasons, playing for both AZ and PSV. He also played in England and Spain, and started and finished his career at Go Ahead Eagles.
Kromkamp was included in the Netherlands squad for the 2006 World Cup.
Kromkamp was first called up by the Dutch national team under coach Marco van Basten, alongside the likes of Dirk Kuyt, Khalid Boulahrouz, Romeo Castelen, Barry Opdam, Hedwiges Maduro and Joris Mathijsen. He won his first cap on 18 August 2004 in a 2–2 draw in a friendly against Sweden and in the following year he established himself as the first-choice right back.
Shortly after Kromkamp's move to Liverpool, however, van Basten admitted that he would rather see the player appear more regularly for his club – labelling the transfer as a bad move. Kromkamp hit back at this criticism by saying that he was very pleased to have joined Liverpool and that he would work hard to make it into van Basten's 2006 FIFA World Cup squad; in May 2006 the manager announced his final list of 23, which included Kromkamp, although he was not used during the tournament itself.
