The start of the new Millennium saw the club win Mullion Cup, which turned out to be the last trophy won by Dunboyne in the AUL (Athletic Union League) before the club decided to transition to the LSL (Leinster Senior League) for the 2002/2003 season.

Dunboyne started their LSL life in Senior 1B, the 4th tier of the Intermediate leagues. After 3 difficult seasons, the club lost its Intermediate status when suffering relegation to Major. The next 4 seasons were spent in the Major League before Dunboyne regained its place in the Intermediate leagues with promotion in the 2008/2009 season. It didn’t take the club long to once again gain promotion as just 2 seasons later Dunboyne were promoted to Senior 1A, the 3 rd level of the Intermediate ladder.

The 2011/12 season saw Dunboyne reach its first Cup final in the LSL however experience told in the final as St. Francis came out victorious to win the Gilligan Cup. They say you have to lose one before you can win one and that proved to be correct as the following season Dunboyne were crowned the 2012/2013 Noel Ryan Cup Winners when coming from behind to secure a late 3-2 victory against St. Josephs Boys just as the game
looked set for extra time.

Two year later, although no silverware was won, you could arguably say the 2014/15 season was the most successful season for Dunboyne in the LSL. A good run saw Dunboyne reach the 4th round of the FAI Intermediate Cup before being defeated by Tolka Rovers in front of a massive crowd up the Summerhill Road.

By reaching this stage of the Intermediate Cup Dunboyne qualified for the FAI Senior Cup for the first time in the clubs’ history. An away game against Killester United stood between Dunboyne and a tie against League of Ireland team Cobh Ramblers. Killester defeated Dunboyne and went on to beat Cobh 3-0 before reaching the quarter-final of the cup which went to underline that LSL clubs could mix it with their LOI counterparts. A win
in Dunboyne’s final league game of the season would have seen the club win the league but a bitterly disappointing draw meant Dunboyne missed out on winning the league but importantly still gained promotion to the second level of Intermediate Football, Senior 1, and the highest level any club in Meath has reached.

After 3 seasons in Sunday Senior 1, the club suffered its first relegation in 13 years as we were demoted back to Senior 1A. The following season saw Dunboyne reach another cup final when they reached the 2018/19 Lummy O’Reilly Cup but lost out to a talented Lucan United team. The club suffered another relegation the following season in what was a Covid interrupted season. The following season never got started due to the pandemic lockdowns but as things start to get back to normal Dunboyne will be looking to have a successful season as they start life in Senior 1B for the 2021-22 season.
