NFL Division 3

The National Football League was first held in 1925–26, thirty-eight years after the first All-Ireland Senior Football Championship. Laois won the inaugural National Football League. The NFL has traditionally played second fiddle to the All-Ireland Senior Football Championship, with most counties using it as preparation for that event. This was not helped by the fact that the league was initially played in winter (usually November–March), while the Championship had the more attractive summer dates and knockout structure.

Mayo dominated the early NFL, winning seven titles in eight seasons until the tournament was suspended during the Second World War. For many seasons in the 1950s and 1960s, the winners of the "home" league played New York in the NFL final; the journey to New York formed an additional prize for the winners. New York won three of these finals.

In 2002, the league was changed to a February–April calendar. This increased interest, boosted attendances and led to live games being broadcast on TG4. The 2009 season was broadcast live on Setanta Sports. Coverage of the 2010 finals in Croke Park saw TG4 become the most watched channel, with 650,000 viewers tuning in to watch some of the games. The Division 1 Final had an average audience of 220,000 viewers.

The National Football League winners receive the Irish National Insurance Cup, first presented to Kerry in 1928–29. Kerry is the most successful team in the competition, having played in the final on twenty-nine occasions and won twenty-three of these. Both of these (final appearances and wins) are records. Kerry also is the team to have most often achieved the "double", by winning both the league title and the All-Ireland Senior Football Championship.
