The 2011 ICF Canoe Slalom World Championships took place from September 7–11, 2011 in Bratislava, Slovakia under the auspices of International Canoe Federation. It was the 34th edition. Bad weather conditions on September 7 and 8 forced the organizers to make changes to the schedule. The events were all held over the remaining three days of the Championships. The women's C1 team event debuted at these championships, but did not count as an official medal event due to insufficient number of participating federations.
