Diving at the 1978 Commonwealth Games

Diving at the 1978 Commonwealth Games was the 11th appearance of the Diving at the Commonwealth Games. The events were held in Edmonton, Canada, from 2 4 to 9 August 1978 and featured contests in four events.

The events were held at the Kinsmen Aquatic Centre, part of the Kinsmen Sports Centre complex. The aquatic centre was constructed in 1976 specifically for the Games.

Canada, as host nation, won the most medals, taking 8, of which 2 were gold. They had a clean sweep of all medals in the women's 3 metre springboard event.

Originally, Linda Cuthbert qualified for the springboard event and Beverly Boys qualified for the high board platform, but decided on a late swap to increase their chances of success. The youngest competitor from Canada competing in the commonwealth games was 18-year-old diver David Snively, then considered "one of Canada's top divers". In the women's 3 metre springboard event, Janet Nutter led all the competitors after the first six dives with 264.27 points, despite battling a cold and laryngitis.
