Keely Nicole Hodgkinson (born 3 March 2002) is an English middle-distance runner. She is the reigning Olympic champion at 800 m after winning the gold medal at the 2024 Summer Olympics. In total, she has won two Olympic medals having won silver at the same distance in the delayed 2020 Games. She is also a two-time European champion in the 800 m and has won two silver medals and a bronze in the same event at World Championship level. She is both the British record holder and the sixth fastest woman ever over 800 m.

At the age of 19, she won the silver medal at the delayed 2020 Summer Olympics, while simultaneously breaking the British record set by Kelly Holmes in 1995. Hodgkinson proceeded to win silver medals at several championships; the 2022 and 2023 World Championships, as well as the 2022 Commonwealth Games. At European level, Hodgkinson went one step higher, becoming a two-time European champion in 2022 and 2024 and a two-time European indoor champion from 2021 and 2023. She also holds the world indoor best for the 600 metres and was the 2021 Diamond League finals 800 m champion.

At the 2024 Summer Olympics, Hodgkinson won the gold medal in the Women’s 800 m. In the final, she led the race from early on, and then broke away in the last 100 metres to cross the line ahead of Tsige Duguma and reigning world champion Mary Moraa. Hodgkinson is also a four-time British national senior champion. She was voted BBC Sports Personality of the Year for 2024, and was awarded an MBE for contribution to athletics in the 2025 New Year Honours list.

Hodgkinson was born on 3 March 2002 in Atherton, Greater Manchester, and brought up there by parents Dean and Rachel. Her mother is also a runner. Hodgkinson attended Fred Longworth High School in Tyldesley, where she was friends with fellow pupil and future England footballer Ella Toone. Hodgkinson also attended Loughborough College in Leicestershire. In 2021, she completed the first year of a criminology degree course at Leeds Beckett University, but later dropped out to become a full-time athlete.

Hodgkinson joined Leigh Harriers at the age of nine and won county championships in 800 m, 1200 m, 1500 m, and cross-country races. She initially swam with Howe Bridge Aces Swimming Club before devoting herself fully to running.

In 2012, aged ten, she competed among seventy finalists at the British Schools Modern Biathlon Championships in London. Hodgkinson finished second in the 500 m run and after the 50 m swim she ended in eighth place overall. Her father encouraged her to focus on athletics, and she was inspired by British heptathlete Jessica Ennis-Hill winning the gold medal at the 2012 London Olympics.

In 2013, she became the first Leigh Harrier to claim the individual U11 girls' title in both the South East Lancashire League and the Red Rose League. She ran her 16th consecutive undefeated race two weeks later, winning on a 2 km course in the Mid-Lancashire Cross Country League at U11 level. On the track, at U13 level, she became Greater Manchester champion in both the 800 and 1200 metres.

In 2014, Hodgkinson won all 13 of her track races (across 800–1500 m events) as well as several cross country competitions. She took her third Greater Manchester title on a 2.75 km cross country course and later defended both her 800 m and 1200 m titles. She broke the championship record in the latter, which had been set in 1985.
