The diving competitions at the 2020 Summer Olympics in Tokyo featured eight events[1] (postponed to 2021[2] due to the COVID-19 pandemic).

For the ninth consecutive Games, China dominated the medal table, and for the fifth occasion in that period won gold in all but a single event; in this case, the 10 metre synchronised men's event won by Great Britain's Tom Daley and Matty Lee.

The United States took third in the medal table, completing a repeat of the top 3 nations from Rio.

Again, as in Rio, China, Great Britain and the United States were also the only nations to medal in 3 or more events.

The following nations have won quota places for the diving competitions.
