Aquatics at the 1930 British Empire Games

At the 1930 British Empire Games in Hamilton, Ontario, Canada, there were two aquatics disciplines – swimming and diving. There were four diving events contested and eleven swimming events. The aquatics programme included the only women's events of the games.

These events were held at the Hamilton Municipal Pool (now the Jimmy Thompson Memorial Pool), which was built specifically for these games. At that time, it was the best competition pool in the British Empire.

England topped the swimming medal table with six gold medals, although Canada equalled the number of six golds by virtue of winning three of the four diving gold medals.
