Jacey Harper (born May 20, 1980) is a male sprinter athlete from Trinidad and Tobago.
A 100 metres specialist, Harper was a part of the Trinidad 4 × 100 m relay teams that won the bronze medal at the 2001 World Championships and the silver medal at the 2005 World Championships. He won the 100 m bronze medal at the 2006 CAC Games.
Following the ruling of December 13, 2005 which retroactively disqualified Tim Montgomery and henceforth the American team from the 2001 Championships, the Trinidad and Tobago athletes were promoted to silver medallists.
