The 2003 Caribbean Football Union Club Championship was an international club football competition held in the Caribbean to determine the region's qualifier for the CONCACAF Champions' Cup. Seven teams from four football associations played in the 2003 edition, contested on a two-legged basis. A round of 16 and a preliminary round were scheduled but never played due to 11 teams withdrawing from the competition.
The Trinidad and Tobago Professional Football League had the edge over the Jamaica National Premier League in the semifinals, winning both ties to set up an all-T&T final. San Juan Jabloteh finally beat W Connection on penalty kicks to advance to the 2004 CONCACAF Champions' Cup.
