Matthew Hudson-Smith (born 26 October 1994) is a British track and field sprinter who specialises in the 400 metres and is the 5th fastest athlete of all-time over the distance.

[5] As of 2022, Hudson-Smith is the most decorated British male athlete in European Championships history, with seven medals, second overall only to French sprinter Christophe Lemaitre.

He was runner-up at the English Schools Championships over that distance in both 2011 and 2012 before finally winning the title in 2013 at the age of eighteen, after returning from a series of hamstring injuries and illness.

On his return to Glasgow for the Commonwealth Games he ran the fastest split on the final leg to overhaul Trinidad and Tobago's Zwede Hewitt and hold off Olympic champion Chris Brown, winning the gold medal for the team.

[12] At the 2014 European Athletics Championships in Zürich, Switzerland, Hudson-Smith won the silver medal in the individual 400 m in a time of 44.75 seconds, behind compatriot Martyn Rooney.

He ran in the heats of the 4x400m relay, but his team were disqualified as Hudson-Smith was judged to have been outside the takeover zone when he started running to receive the baton from Delano Williams.

[16] He won bronze as part of the men's 4x400m relay, with his teammates Dwayne Cowan, Rabah Yousif and Martyn Rooney[17] Prior to the 2018 season, he moved to Florida and started working with Coach Lance Brauman and the PureAthletics camp which also featured the likes of Noah Lyles and Shaunae Miller-Uibo.

However, in the 2022 season Hudson-Smith switched coaching groups to partner with Gary Evans and returned to his best form breaking the British national record at the Prefontaine Classic in Eugene clocking 44.35 seconds and being signed by Puma.

[citation needed] In 2023, he won the silver medal in the men's 400m at the 2023 World Athletics Championships, again breaking the European record in the semi-finals with a time of 44.26.

Hudson-Smith married Antonia Tyson at a ceremony in Birmingham, England, on 29 September 2024, with guests at the event including Dina Asher-Smith and Noah Lyles.
