Trinidad & Tobago made its Olympic debut in 1948 and, between 1948 and 2012, the Trinidad & Tobago Olympic Committee selected a cumulative total of 240 participants to represent the country at the 17 Olympics. Since some of the selectees competed in more than one Olympics, the 240 slots have been filled by a total of 169 athletes. Over the years, the 240 participants (190 male and 50 female) competed in ten different sports: athletics; badminton; boxing; cycling; shooting; swimming; table tennis; taekwondo; weightlifting; and yachting. Acknowledgment is given to Bernard Linley for his meticulous attention to, and additional information provided on, the significant accomplishments of the T&T olympians over the years.
