What is Usain Bolt's full name?

Usain Bolt's full name is Usain St. Leo Bolt.

He was born on 21 August 1986 in Sherwood Content, a small community in Jamaica's Trelawny parish. His parents, Wellesley and Jennifer Bolt, ran a local grocery store. Bolt's middle name, St. Leo, was given to him by his aunt, while his first name was suggested by a relative.

Bolt became famous as a sprinting prodigy, eventually setting world records in the 100 metres, 200 metres and 4 × 100 metres relay. His nickname, “Lightning Bolt,” reflects both his surname and his extraordinary speed. He is also widely known simply as Usain Bolt, so quiz questions asking for his “full name” are testing the middle name that is often omitted.

A common mix-up is assuming that “St. Leo” is a nickname or a second surname. It is his given middle name, making “Usain St. Leo Bolt” the canonical full-name answer.
