The 2008 TT Pro League was the tenth season of the TT Pro League, the Trinidad and Tobago professional league for association football clubs, since its establishment in 1999. A total of ten teams took part in the league, with San Juan Jabloteh the defending champions. The season began on 5 April and ended on 29 November, with the conclusion of the Lucozade Sport Big Six.
Ma Pau were admitted as a new club into the league and would be based in Woodbrook. After one season upon their return to the Pro League, Police withdrew with the intention of returning for the 2009 season. The Superstar Rangers decided to change the name of the club to St. Ann's Rangers to increase community awareness.
The first goal of the season was scored by San Juan Jabloteh's Peter Byers against Ma Pau in the sixth minute of the first game on 5 April. Devorn Jorsling, who also scored on the first day, went on to claim the Golden Boot with a season high 21 goals. Josimar Belgrave of St. Ann's Rangers scored the first hat-trick of the season against Tobago United on 3 May, having scored a season high four goals in the match.
Following the regular season, San Juan Jabloteh, W Connection, Caledonia AIA, Joe Public, North East Stars, and United Petrotrin all qualified for the Lucozade Sport Big Six. However, Jabloteh and W Connection were 20 points clear of third place, Caledonia AIA, before the competition began. The league was won on the final day of the season, when the San Juan Kings used a draw over W Connection to defend their crown and win their fourth Pro League title.
