(Sugar) Jackson Osei Bonsu (born 3 March 1981, in Ghana) is a Belgian welterweight professional boxer of Ghanaian descent.
Jackson has, in recent times, gained a large following in the UK and US, and in early 2008 was voted the 'Official Overseas Fighter' of internet boxing forum Boxing Rebels, replacing the charismatic Bobby Gunn.
On 14 September 2008 Jackson lost his EBU Welterweight title in a greatly disputed unanimous decision against Rafał Jackiewicz.
Although all three judges scored the fight in favour of Jackiewicz, there was great controversy as many experts believed Sugar Jackson won at least 10 of the 12 rounds.
Belgian newspaper De Standaard called the result 'the theft of the century'.
