The Louth Junior A Football League, or Division 3 of the county football Leagues, is an annual Gaelic football competition. Introduced in 1921, it is contested by Junior clubs in County Louth. The captain of the winning team is presented with the Dixon Cup.
A Final to determine the winner was held annually until 1996, when the format changed. At the end of the league programme, the team with the most points is now awarded the trophy and is promoted to Division 2. The second-placed team can obtain promotion by winning a play-off involving a Division 2 club. Division 3 was split into separate A and B grades in 2019, before returning to the old format in advance of the 2025 season.
The MacArdle Cup was presented to each winning team until 2014, when it was replaced by the Dixon Cup.
