Adam Gemili (Persian: آدام جمیلی; born 6 October 1993) is a British sprinter from England. He is the 2014 European champion at 200 metres, and 4 x 100 metres relay, and part of the Great Britain team that won gold in the 2017 World Championships in the same event.
A silver medalist in the 100 metres and 4 × 100 m relay in the 2014 Commonwealth Games, Gemili is also a former World Junior champion at 100 m and European Under-23 champion at 100 m and 4 × 100 m relay.
Gemili won a gold medal over 100 m at the 2012 World Junior Championships in Athletics in Barcelona. His winning time of 10.05 seconds established a new championship record, and is the second fastest ever run by a European junior, behind only Christophe Lemaitre (10.04). Having cleared the Olympic qualifying time with his 10.08 seconds in the 100 m in June 2012, Gemili competed at the 2012 Summer Olympics where he, after a poor start, came third in the semi-final in a time of 10.06 s, 0.04 s short of qualifying for the final.
