Trinidad and Tobago football clubs in international competition

Trinidad and Tobago football clubs have entered international competitions since 1967, when Regiment of the Port of Spain Football League took part in the 1967 CONCACAF Champions' Cup. Since the nation's first international club competition, several association football clubs from Trinidad and Tobago have entered North America, Central America, and Caribbean competitions (CONCACAF Champions' Cup/Champions League and CFU Club Championship).

The CONCACAF Champions' Cup started in 1962, but there was no Trinidad and Tobago representative during that inaugural season as the competition was open to eight teams from seven countries: Netherlands Antilles, Costa Rica, El Salvador, Guatemala, Haiti, Honduras, and México. Since their first appearance, Trinidad and Tobago clubs have claimed the Champions' Cup on two occasions with Defence Force winning the title in 1978 and again in 1985 in the Teteron Boys' treble-winning season.

Since the establishment of the CFU Club Championship in 1997, clubs from the Caribbean Islands that are members of the Caribbean Football Union, have competed in the region's qualification tournament for the CONCACAF Champions' Cup and Champions League. The first club to compete in the regional competition was United Petrotrin of the Semi-Professional League. The Oilmen won the inaugural tournament after defeating Seba United of Jamaica 2–1 to advance to the 1997 Champions' Cup. Since the country's first appearance in the CFU Club Championship, Trinidad and Tobago clubs have claimed the title on eleven occasions with an additional nine runners-up finishes.

TT Pro League international performance
Since the inaugural season of the TT Pro League in 1999, the league champion and runners-up have entered the CFU Club Championship to earn qualification in the CONCACAF Champions' Cup/Champions League. The first Pro League club to compete in international competition was Joe Public when the club entered the 1999 CONCACAF Champions' Cup. However, the Eastern Lions qualified for the competition through the 1998 CFU Club Championship as a member of the Semi-Professional League the previous season. The 2000 CFU Club Championship was the first occurrence of clubs having earned qualification through final position in the Pro League. Defence Force entered as the 1999 Pro League champion, W Connection as runners-up, and Joe Public as the CFU Club Championship holders. Joe Public won the competition to provide the Pro League with its first international championship.

Pro League clubs have won the CFU Club Championship for Caribbean-based clubs on eleven occasions and nine additional runners-up finishes. However, no Pro League club has won the Champions' Cup or Champions League. The best performance occurred in the 2000, 2004, and 2007 Champions' Cup when Joe Public, San Juan Jabloteh, and W Connection, respectively, entered the quarterfinal round.

CONCACAF Champions' Cup and Champions League
Note: The CONCACAF Champions' Cup began in 1962 and was renamed the CONCACAF Champions League in 2008–09 (abbreviated here to 2009). Trinidad and Tobago clubs began entering the continental competition in 1967. After the inauguration of the TT Pro League in 1999, teams from the Pro League were playing in CONCACAF competition during that season (abbreviated to 2009), even though they had actually qualified through the old Semi-Professional League the previous season.

For comparison, this table shows how Trinidad and Tobago clubs have performed at the top level of CONCACAF football before the TT Pro League era. Defence Force remains the only team from Trinidad and Tobago to win the Champions' Cup in 1978 and 1985. Since the Teteron Boys' treble-winning season, the best performance by a Trinidad and Tobago team came in 1987 and 1988 when Defence Force, and again in 1991 when Police finished as runners-up.
