Usain St Leo Bolt (born 21 August 1986) is a Jamaican sprinter. He is the first person to hold both the 100 metres and 200 metres world records since fully automatic time became mandatory. He also holds the world record as a part of the 4 × 100 metres relay. He is the reigning world and Olympic champion in these three events. Due to his unprecedented dominance and achievements in sprint competition, he is widely considered to be the greatest sprinter of all time.

An eight-time Olympic gold medalist, Bolt won the 100 m, 200 m and 4 × 100 m relay at three consecutive Olympic Games, although he subsequently lost one of the gold medals (as well as the world record set therein) nine years after the fact due to teammate Nesta Carter's disqualification for doping offences. He gained worldwide popularity for his double sprint victory at the 2008 Beijing Olympics in world record times. Bolt is the only sprinter to win Olympic 100 m and 200 m titles at three consecutive olympics (2008, 2012 and 2016), a feat referred to as the "triple double."
