Here’s the list of all Olympic finishes for each country over the history of the sport starting in 1984, the first time synchronized swimming was in the Olympic Games. If a year is not listed in the table, the country did not participate that year. If a nation does not appear on this page, it simply means it has not competed in the Olympics yet.
As a reminder, the 1984, 1988 and 1992 Games only had solo and duets. Teams first appeared at the Olympics in 1996, and were the only event that year. The solo event was discontinued after the 1992 Olympics.
The number of nations allowed in each event has also changed over the years. As of 2024, 10 teams and 18 duets could participate.
