The 2024 Summer Olympics (French: Les Jeux Olympiques d'été de 2024), officially the Games of the XXXIII Olympiad (French: Jeux de la XXXIIIe olympiade de l'ère moderne) and branded as Paris 2024, were an international multi-sport event held in France from 26 July to 11 August 2024, with several events started from 24 July. Paris was the host city, with events (mainly football) held in 16 additional cities in metropolitan France, including the sailing centre in the second-largest city of France, Marseille, on the Mediterranean Sea, as well as one subsite for surfing in Tahiti, French Polynesia.

Paris was awarded the Games at the 131st IOC Session in Lima, Peru, on 13 September 2017. After multiple withdrawals that left only Paris and Los Angeles in contention, the International Olympic Committee (IOC) approved a process to concurrently award the 2024 and 2028 Summer Olympics to the two remaining candidate cities; both bids were praised for their high technical plans and innovative ways to use a record-breaking number of existing and temporary facilities. Having previously hosted in 1900 and 1924, Paris became the second city ever to host the Summer Olympics three times (after London, which hosted the games in 1908, 1948, and 2012). Paris 2024 marked the centenary of the 1924 games and the 1924 Winter Olympics in Chamonix (the first Winter Olympics), as well as the sixth Olympic Games hosted by France (three Summer Olympics and three Winter Olympics) and the first with this distinction since the 1992 Winter Games in Albertville. The Summer Games returned to the traditional four-year Olympiad cycle, after the 2020 edition was postponed to 2021 due to the COVID-19 pandemic.

Paris 2024 featured the debut of breaking as an Olympic sport, and was the final Olympic Games held during the IOC presidency of Thomas Bach. The 2024 Games were expected to cost €9 billion. The opening ceremony was held outside of a stadium for the first time in modern Olympic history, being outdoors in the Paris's downtown and with as athletes were paraded by boat along the Seine.
