Usain St Leo Bolt, OJ (Order of Jamaica), CD (Order of Distinction) born on 21 August 1986 is a Jamaican former sprinter, widely considered to be the greatest sprinter of all time. He is a world record holder in the 100 meters, 200 meters and 400 meters relay.

His achievements as a sprinter have earned him the media nickname "Lightning Bolt", and his awards include the IAAF World Athlete of the Year, Track & Field Athlete of the Year, BBC Overseas Sports Personality of the Year (three times) and Laureus World Sportsman of the Year (four times). Bolt retired after the 2017 World Championships, when he finished third in his last solo 100 m race, opted out of the 200 m, and pulled up in the 4×100 m relay final. Bolt has the nickname "Lightning Bolt" due to his name and speed. He is Catholic and known for making the sign of the cross before racing competitively, and he wears a Miraculous Medal during his races. His middle name is St. Leo.

He popularized the "lightning bolt" pose, also known as "to di world" or "bolting", which he used both before races and in celebration. The pose consists of extending a slightly raised left arm to the side and the right arm folded across the chest, with both hands have the thumb and index finger outstretched. His performance of the pose during his Olympic and World Championship victories led to widespread copying of the move, from American President Barack Obama to small children.
