Dušan Kožíšek is a Czech cross-country skier who has been competing since 2002. He won a bronze medal in the team sprint at the 2005 FIS Nordic World Ski Championships in Oberstdorf and finished 38th in the individual sprint in those same games. Kožíšek repeated the success in the team sprint at the 2007 FIS Nordic World Ski Championships in Sapporo when he won a bronze medal, this time with Milan Šperl. Kožíšek also finished 17th in the individual sprint at those same games.

The FIS Nordic World Ski Championships 2007 took place 22 February – 4 March 2007 in Sapporo, Japan. It was the second time this city has hosted these championships, having previously done so in the 1972 Winter Olympics. Sapporo was selected as venue by vote at the 43rd FIS World Congress in Portorož, Slovenia, on 6 June 2002. It also marked the third time the championships were hosted outside Europe in a year that did not coincide with the Winter Olympics; it was the first championship held in Asia. The ski jumping team normal hill event was not held, as it had been in 2005.
