Mattia Furlani (born 7 February 2005) is an Italian long jumper, the 2025 outdoor and indoor world champion and the bronze medallist at the 2024 Paris Olympic Games.
Furlani is a son of the former high jumper Marcello Furlani (personal best of 2.27 m) who is also his coach. He is of Senegalese descent through his mother, Khaty Seck (a former sprinter). His sister Erika (born 1996) is a high jumper (1.94 m personal best).
In 2022, Furlani won two gold medals at the European U18 Championships in Jerusalem, in the high jump and in the long jump.
On 29 January 2023, still 17, he broke the European U20 indoor long jump record with a leap of 7.99 m for second place at the Folksam Grand Prix in Stockholm, Sweden. In March, he competed in the senior long jump contest at the European Indoor Championships in Istanbul, where he did not advance to the final. On 24 May, Furlani soared at 8.44 m in the long jump competition at the Meeting di Savona on home soil. It would have been the world U20 record if the wind had not been just above the legal limit at 2.2 m/s, with his mark being the longest in history by an U20 athlete in all conditions.
In the 2024 Paris Olympics, Furlani jumped 8.34 m in his first jump, which was enough to take home the bronze medal. He jumped a World U20 record of 8.38 m that year in Rome. He also jumped a World U20 indoor record with 8.34 in Ancona in the same year.
He won the silver medal in the long jump at the 2025 European Athletics Indoor Championships with a jump of 8.12 metres, just one centimetre behind gold medal winner Bozhidar Sarâboyukov. It reversed a result from the 2023 European Athletics U20 Championships where the Italian won gold by a single centimetre with 8.23 m from Sarâboyukov.
At the 2025 World Indoor Championships, Furlani won the gold medal with a 8.30 m jump, just one centimetre more than silver medalist Wayne Pinnock.
A few months later, at the 2025 World Championships in Tokyo, Furlani won the gold medal again with a 8.39 m jump, becoming the youngest long jump world champion ever by doing so.
Furlani won a national championship at individual senior level.
