The triathlon competitions at the 2024 Summer Olympics in Paris ran from 31 July to 5 August at Pont Alexandre III, featuring a total of 110 athletes who were to compete in each of the men's and women's events.

[1][2] After a successful debut at the 2020 Summer Olympics, the mixed relay competition will remain in the triathlon program for the second time.

[4] As the host country, France automatically receives four quota places (two per gender) while the highest-ranked eligible NOC will each obtain two men's and two women's spots at the 2022 and 2023 Mixed Relay World Championships.

The final two spots per gender are awarded to the triathletes under the Tripartite Commission and to those eligible in the top 180 of the World Triathlon individual rankings.

The men's individual event was originally scheduled for 30 July 2024 but was postponed when the water quality in the Seine failed a safety test for levels of pollution.
