The 18th Central American and Caribbean Junior Championships were held in the Estadio Olímpico Félix Sánchez in Santo Domingo, Dominican Republic, between 2–4 July 2011, and organized by the Federación Dominicana de Asociaciones de Atletismo (FDAA).

[3][4] Events marked as "Exhibition" did not meet the official conditions with respect to the minimum number of participants ("not less than five (5) competitors of three (3) countries").

[1] In the Male Junior B category, there is no information on the originally scheduled events "5000 m race walk" and "octathlon".

‡: Javari Fairclough from Jamaica had the second best performance of 7.11m, while the second best jump of Juan Mosquera from Panamá was only 6.97m.

Working through the results,[3][4] an unofficial count yields the number of about 500 athletes (205 junior, 195 youth) in the start list.
