The FIBT World Championships 1939 took place in St. Moritz, Switzerland (Two-man) and Cortina d'Ampezzo, Italy (Four-man). St. Moritz hosted the two-man event for the second time after hosting it previously in 1938, along with hosting the four-man event in 1931, 1935, and 1937. Cortina d'Ampezzo hosted the two-man event previously in 1937. It was the last world championships that would be held prior to World War II and the last that would be held with bobsleigh events in separate locations until 2000 when the two-woman event debuted that year.
