Sophie Megan Hahn (born 23 January 1997) is a parasport athlete from England competing mainly in T38 sprint events.

In 2018, she won the gold medal in the T38 100 metres for women at the Commonwealth Games; in doing so she became the first female track and field athlete to hold gold medals in the same event from the World Championships, Paralympic Games, European Championships and Commonwealth Games, mirroring in parasports the achievements of fellow Paralympian Dan Greaves, and Olympic champions Daley Thompson, Linford Christie, Sally Gunnell, Jonathan Edwards and Greg Rutherford.

Enthused by the 2012 Summer Paralympics in London, her older brother, knowing of her pace as a runner encouraged her to seek an athletics club.

Her mother got in touch with her nearest club and Hahn was called in for trials and accepted by coach Joseph McDonnell.

After entering several tournaments in June, she broke onto the British sprinting scene by taking first place at the England Athletics Senior Disability Championships, winning both 100m (13.27s) and 200m (27.88s).
