Usain St. Leo Bolt (born 21 August 1986) is a Jamaican sprinter. Regarded as the fastest person ever, he is the first man to hold both the 100 metres and 200 metres world records since fully automatic time measurements became mandatory in 1977. Along with his teammates, he also set the world record in the 4×100 metres relay. He is the reigning Olympic champion in these three events, the first man to win six Olympic gold medals in sprinting, and an eleven-time World champion. He was the first to achieve a "double double" by winning 100 m and 200 m titles at consecutive Olympics (2008 and 2012),and topped this through the first "double triple" (including 4×100 m relays).

Although gaining worldwide popularity for a sprint double victory at the Beijing Games, Bolt has had more victories as a 200 m runner. While he had not won any significant 100 m title prior to the 2008 Olympics, he had won numerous crowns in the 200 m event at the youth, junior and senior levels. Further, at the 2013 World Championships in Moscow, Bolt completed a hat-trick of 200 m world titles by winning his third straight gold in the event. His 2009 record breaking margin for 100 m, from 9.69 seconds (his previous world record) to 9.58, is the highest since the start of fully automatic time measurements

Bolt's achievements in sprinting have earned him the media nickname "Lightning Bolt", and awards including the IAAF World Athlete of the Year, Track & Field Athlete of the Year, and Laureus World Sportsman of the Year (three times). He is the highest paid athlete ever in track and field. He has been called the world's most marketable athlete. By winning three gold medals at the 2015 World Championships, Bolt became the first athlete to complete a "triple triple", and also became the most successful athlete in the 32-year history of the athletics world championships.
