The FIS Nordic World Ski Championships 2011 took place from 23 February to 6 March 2011 in Oslo, Norway. The championships consisted of 21 events in cross-country skiing, ski jumping and Nordic combined, of which eight were team or relay events. The tournament was held at Holmenkollen National Arena, with ski jumping in the large Holmenkollbakken and the normal Midtstubakken, and coincided with the Holmenkollen Ski Festival. Since the 2009 World Championships, a normal hill team event was added for both ski jumping and Nordic combined, while the combined mass start was removed from the program.
