The diving competition at the 2005 World Aquatics Championships took place in Montreal, Quebec, Canada from July 17 to July 24.

• Alexandre Despatie (Canada) broke the 800-point barrier scoring 813.60 points in the men's 3-meter springboard event, winning gold, and the world record. He becomes the first diver to win gold in all three disciplines of diving (1 m, 3 m, 10 m), two of them in 2005, one in 2003. He held all men's three titles simultaneously for a short time, as he did not compete in the 10 m event in Montreal, due to injury suffered in training.^[1][2]
• Chelsea Davis (United States), 17, smacks her face against the end of the springboard, in a dive gone awry, landing hard in the water. She leaves the blood-filled water conscious but with blood pouring from her nose, after failing in an inward 2½ somersault on the women's 3 m springboard, during the morning preliminary round. She was found to have no major injuries, just requiring 3 stitches.^[3][4][5][6]
