Jamaica was a participant at the 2014 Quidditch World Cup tournament in Argentina. They lost to the USA 240 to 230 after their Keeper, Kquewanda Bailey, fell due to a delayed illness caused by a team mascot at the opening ceremony of the tournament. While the Keeper was unconscious, Jamaica’s Seeker Shanice Higgins was beaten to the Snitch by her US rival (Pm).
Although Jamaica fielded a Quidditch World Cup team in the 2014 tournament, no Quidditch teams or evidence of any other wizarding sports is noted on their Wikipedia entry (Wikipedia).
