The 2001 World Aquatics Championships or the 9th FINA World Swimming Championships were held in Fukuoka, Japan between 16 July and 29 July 2001.

The opening and closing ceremonies, as well as the swimming and synchronised swimming events, were held at Marine Messe, an indoor multi-purpose facility. The temporary 50-m pool with 10,000 seats on three sides cost US$4 million for the two-week period. The Fukuoka Prefectural Pool hosted the diving events, with open water swimming taking place at Momochi Beach. Water polo was held at two locations: the men's competition took place at Hakata-no-Mori Center Court and the women's event at the Nishi Civic Pool.
