Usain Bolt was born in Trelawny, a parish in northwestern Jamaica. His birthplace was Sherwood Content, a small rural community in Trelawny Parish.
Bolt was born on 21 August 1986 to Wellesley and Jennifer Bolt. He grew up in the nearby village of Sherwood Content, where his parents ran a small grocery store. As a child, he developed an interest in cricket and football before athletics became his dominant sport.
Trelawny is one of Jamaica's fourteen parishes and is known for its mountainous interior, coastal areas and historic settlements. The parish is named after William Trelawny, a former governor of Jamaica.
Kingston is often associated with Bolt because it became the centre of his training and international career, but it is not his birthplace. The more precise answer is Sherwood Content, while Trelawny is the correct parish-level answer asked for here.
