The ICF Canoe Slalom World Championships are an international event in canoeing organized by the International Canoe Federation. The World Championships have taken place every year in non-Summer Olympic years since 2002. From 1949 to 1999, they had taken place in odd-numbered years. The 2001 championships were scheduled to take place in Ducktown, Tennessee from 20 to 23 September, but were canceled in the wake of the September 11 attacks.
