Emma Finucane (/fɪˈnuːkən/ fin-OO-kən; born 22 December 2002) is a Welsh track cyclist. She is an Olympic gold medalist in the team sprint, a two-time world champion and one-time European champion in the sprint, and a world and European champion in the team sprint. At the 2024 Summer Olympics, she became the first British woman to win three medals at a single games since Mary Rand in 1964.

In 2019, Finucane became the Junior European champion in the 500 m time trial. At the senior level, Finucane won two bronze medals for Wales at the 2022 Commonwealth Games, in the sprint and the team sprint, and she became a world champion for the first time at the 2023 World Track Cycling Championships when she triumphed in the sprint. Her victory made her the third British woman to become world sprint champion, after Victoria Pendleton and Becky James. Finucane enjoyed further success in 2024, becoming the European champion in the sprint, winning three gold medals at the Track Cycling Nations Cup in Hong Kong, and then winning her first Olympic gold medal at the 2024 Summer Olympics in Paris. There, she was a member of the British team sprint line-up who set a new world record on their way to gold, and she added two further bronze medals in the sprint and the keirin. She completed 2024 by becoming a world champion in the team sprint for the first time, and she also successfully defended her world sprint title.

Finucane grew up in the caretaker's house at Picton Barracks in Carmarthen, Wales. She attended St John Lloyd Catholic Comprehensive School in Llanelli, and she started cycling at aged eight at Carmarthen Velodrome, where she cycled with her sister and brother. She then joined local club Towy Riders before later training at the Wales National Velodrome in Newport. She has since revealed that Welsh cyclist Nicole Cooke was her idol while she was growing up.

Finucane was spotted by British Cycling in 2018, and that same year she won four national titles in the under-16 category. They came in the 500 m time trial, sprint, scratch race and madison disciplines. In 2019, she became Junior European Champion in the 500 m time trial as well as finishing runner-up in both the sprint and team sprint. Finucane then won bronze medals in the sprint and the 500 m time trial disciplines at the 2019 UCI Junior Track Cycling World Championships in Frankfurt. Two years after she was first spotted by British Cycling, she moved to Manchester, the home of the National Cycling Centre.

Finucane won two silver medals at the 2020 British National Track Championships, which came in the 500 m time trial and keirin, respectively. In 2021, she won silver in the team sprint at the UEC Under-23/Junior Track European Championships in Apeldoorn. Racing alongside Rhian Edmunds and Lowri Thomas, Finucane became a senior national champion for the first time with victory in the team sprint at the 2022 British National Track Championships. She also won a silver medal in the keirin and bronze medals in both the sprint and the 500 m time trial. Representing Wales, Finucane, Thomas and Edmunds finished in third position in the team sprint at the Track Nations Cup meeting in Glasgow.

Again representing Wales, Finucane won two bronze medals at the 2022 Commonwealth Games in Birmingham. She overcame Sophie Capewell of England in the bronze medal race in the sprint, and competing alongside Edmunds and Thomas, she claimed bronze in the team sprint. Finucane described her two medals as "above and beyond" her expectations. She then made her debut appearance at the UCI Track Cycling World Championships in October. Competing for Great Britain, she helped secure bronze in the team sprint with Lauren Bell and Capewell.

Finucane won four national titles at the 2023 British Cycling National Track Championships, taking her career total of national titles to five. Her victories came in the 500 m time trial, the sprint, the keirin and the team sprint (with Katy Marchant and Milly Tanner). At the 2023 UEC European Track Championships in Grenchen, Finucane won silver medals in both the team sprint and the keirin. In the Track Cycling Nations Cup, Finucane won bronze medals in the sprint and team sprint at the first round in Jakarta, before claiming sprint gold at the next round in Cairo.

At the 2023 UCI Track Cycling World Championships in Glasgow, she claimed her first senior world title as she took gold in the sprint competition. Her success made her the first British woman to become the world sprint champion since Becky James in 2013, and the third British woman overall (after Victoria Pendleton and James). She sealed victory by beating German rider Lea Friedrich in the final. Finucane also set a new sea level record time during her 200 m qualifying ride for the sprint. Later in the competition, she was a member of the British trio who claimed silver in the team sprint. Finucane was named 2023 BBC Cymru Wales Sports Personality of the Year.
