1989–90 National Football League (Ireland)

The 1989–90 National Football League, known for sponsorship reasons as the Royal Liver Assurance National Football League, was the 59th staging of the National Football League (NFL), an annual Gaelic football tournament for the Gaelic Athletic Association county teams of Ireland.

The tournament introduced several experimental rules: game divided into four quarters; all kick outs from the hands from within the small rectangle; free kicks from the hands or the ground; all sideline kicks from the hands; teeing up the ball is a foul. Of these rules, only the free kick from hand or ground, and the illegality of teeing up the ball, survive to the modern day. Meath defeated Down in the final.
