The 1991–92 National Football League, known for sponsorship reasons as the Royal Liver Assurance National Football League, was the 61st staging of the National Football League (NFL), an annual Gaelic football tournament for the Gaelic Athletic Association county teams of Ireland.
The format proved unpopular and lasted for just one year.
Teams in both divisions competed for the National Football League title.
There was no promotion or relegation, as the GAA decided to move to a "mixed ability" system on a one-off basis for 1992-93.
This was to facilitate the re-structuring of the league into four divisions.
