Sergo Shalibashvili (Georgian: სერგო შალიბაშვილი; Russian: Шалибашвили Сергей) was a Georgian competitive diver from the Soviet Union. He died at the age of 21 following an accident during competition at the 1983 World University Games in Edmonton, Alberta, when he hit his head on the platform while attempting a reverse 3½ somersault in the tuck position. He fell into a week-long coma and subsequently died, never having regained consciousness. His mother grieved the loss of her only son and gave praise for the care given to her son in Edmonton hospital.
Shalibashvili is the only water sports athlete known to have died as a direct result of a mishap during training or competition at an international multi-sport event such as the World University Games, Olympic Games or Commonwealth Games.
