Diving at the 2020 Summer Olympics – Women's synchronized 3 metre springboard

The women's synchronized 3 metre springboard diving competition at the 2020 Summer Olympics in Tokyo was held on 25 July 2021 at the Tokyo Aquatics Centre. It was the 6th appearance of the event, which had been held at every Olympic Games since the 2000 Summer Olympics.

The medals for the competition were presented by Nicole Hoevertsz, Aruba; IOC Executive Board Member, and the medalists' bouquets were presented by Dale Neuburger, United States; FINA Treasurer and a Gift Presenter.

Competition format
The competition was held in a single round, consisting of each pair performing five dives. Each dive was from a different group (forward, back, reverse, inward, and twisting). The first two dives were given a fixed degree of difficulty of 2.0, regardless of the dive performed. The other three dives were assigned a degree of difficulty based on somersaults, position, twists, approach, and entry. There was no limit to the degree of difficulty of dives; the most difficult dives calculated in the FINA rulebook (reverse 4 $1/2$ somersault in pike position and back 4 $1/2$ somersault in pike position) was 4.7, but competitors could attempt more difficult dives. Scoring was done by a panel of eleven judges, with five judges evaluating synchronization and three judges evaluating execution of each individual diver. For each dive, each judge gave a score between 0 and 10 with 0.5 point increments. The top and bottom synchronization scores and the top and bottom execution scores for each diver were discarded. The remaining five scores were summed, multiplied by $3/5$, and multiplied by the degree of difficulty to give a dive score. The five dive scores were summed to give the score for the round.
