Here, the PA news agency picks out 10 stars who are expected to shine.
Sky Brown
Britain’s skateboard superstar claimed an historic bronze medal at the delayed Tokyo 2020 Olympics and will head to Paris as the reigning world champion in the park category. Still only 15, Brown has still not given up hope of also representing Team GB in the Olympic surfing event in Tahiti.
Simone Biles
One of the world’s greatest ever gymnasts launched a spectacular return in 2023, after an extended hiatus to prioritise mental health. With a remarkable four world golds, including in the prestigious women’s all-around, Biles once again set her stall out as the star to watch in Paris.
Noah Lyles
The US track star dazzled in 2023, winning gold in both 100m and 200m at the World Championships in Budapest. Looking to build on the 200m bronze he took in Tokyo, Lyles is intent on expanding his horizons by potentially also forming a part of the men’s 4x400m relay squad.
Jude Bellingham
England’s Bellingham has made a stunning start to his Real Madrid career, scoring 12 goals in his first 14 LaLiga appearances and also becoming the first player to score in each of his first four Champions League appearances for the club. A sensational platform at Euro 2024 in Germany awaits.
Sam Walters
The 6ft 6ins Walters was one of the more dependable figures in another testing rugby league season for Leeds Rhinos, so it came as a great surprise that he was allowed to leave to join rivals and reigning Super League champions Wigan. Walters’ speed and power can only make the champions stronger.
Jannik Sinner
Speedy baseliner Sinner has been threatening to move into serious grand slam title contention for some time and the signs are that 2024 could be his year. Sinner won two of four meetings with Novak Djokovic – including a dramatic Davis Cup rubber – and more of the same is seemingly assured for 2024.
Luca Brecel
He probably will not practice and will be one of the first to write off his chances. But enigmatic Belgian Luca Brecel will return to the Crucible in April as the defending world snooker champion – and one of the few top-level current players who can boast the stamina to get to the end of the 17 gruelling days.
Kylian Mbappe
Mbappe might not be in the best of moods in relation to his club career but his importance to France – and his ability to light up the game’s biggest stages – will be in evidence during Euro 2024. Moreover, Mbappe still harbours hopes of appearing as an over-age player at the Paris Olympics.
Keely Hodgkinson
So far it has been a career of so near yet so far for the British 800 metres ace, who has had to settle for silver medals at consecutive world championships, as well as the Tokyo Olympics and the Birmingham Commonwealth Games. All eyes will be on her bid to go one better in Paris.
Nat Sciver-Brunt
The all-rounder, who has landed a deal to play for Perth Scorchers in the next women’s Big Bash, will play a pivotal role when England are scheduled to head to Bangladesh in 2024 as one of the favourites to clinch the women’s T20 world title.
There has been plenty of excitement around the home nation heading into the men's Olympic tournament, with coach Thierry Henry selecting a strong squad even with superstars like Kylian Mbappe absent.
Yet it took more than an hour for the match in Marseille to spark into life, and even then France were reliant on a moment of magic from captain Alexandre Lacazette.
The United States were the better side up until Lacazette's breakthrough goal, with Djordje Mihailovic thundering against the crossbar shortly before the veteran striker went up the other end and picked out the bottom-left corner.
A frantic spell followed in which France twice could have been pegged back, grateful first to Guillaume Restes for a superb save from Paxten Aaronson and then to the goal frame as John Tolkin headed against the post.
Instead, a second goal against the run of play settled the nerves in the stands as Bayern Munich new boy Michael Olise curled a fine finish around Patrick Schulte from outside the box.
And Loic Bade added further gloss with a header from a Joris Chotard corner five minutes from time, while Griffin Yow saw a late consolation goal struck off for offside.
Data Debrief: Belated home comfort for Les Bleus
On paper, the gulf between the two teams was evident in the scoreline, but for those home fans in Marseille who grew audibly agitated early in the second half, this was far from easy viewing.
Although France finished with three goals, they only created chances worth 0.43 expected goals (xG). The strikes by Lacazette and Olise were inspired individual efforts rather than the result of fine team play.
Winning gold as the hosts is not easy in this event – only four nations (Great Britain in 1908, Belgium in 1920, Spain in 1992 and Brazil in 2016) have done so previously in 27 attempts – but more will be expected of Henry's outfit going forward.
Thierry Henry, who is the coach of Les Bleus' under-23 side, did not include the Paris Saint-Germain forward, who is expected to complete a move to Real Madrid in the coming days following Los Blancos' 15th Champions League success.
The 46-year-old has until July 3 to confirm his final 22-player list ahead of group-stage fixtures against the United States on July 24, Guinea on July 27 and New Zealand on July 30.
Henry has revealed he faced plenty of difficulties when selecting his squad, with several clubs refusing to release their players for the tournament.
Because the football event at the Olympics is not formally recognised by FIFA, clubs are not obliged to release their players for the competition, which begins on July 24 and ends on August 9.
"Real Madrid were really straightforward about the Olympics," Henry said when quizzed about Mbappe's omission from the squad.
"The last time I received so many rejections was at the university. There have not even been negotiations. You go, you ask, they say no, and you leave."
Henry was able to include several talented stars from across European football, including Crystal Palace duo Michael Olise and Jean-Philippe Mateta, while Bayern Munich's Mathys Tel and PSG's Warren Zaire-Emery were among the other high-profile inclusions.
However, Chelsea stars Malo Gusto and Benoit Badiashile were refused release from Stamford Bridge, but the Blues were able to offer midfielder Lesley Ugochukwu.
Asked if he was disappointed by the decisions made by Premier League clubs, Henry replied: "I will respond to this one very, very clearly – it's not the time for me to talk about that, firstly.
"Secondly, am I disappointed or surprised? No. Neither disappointed nor surprised, the clubs are within their rights, unfortunately, and I think what I have been saying hasn't changed since I started talking about the Olympics."
Les Bleus have previously won two medals at the Olympic Games, taking silver on home soil in Paris back in 1900 and gold at Los Angeles in 1984.
The rules of the competition state that each team must be made up of players born on or after January 1, 2001 (aged 23 at the time of the Games). However, three players born before that date can also be included.
