The 1970–71 National Football League was the 40th staging of the National Football League (NFL), an annual Gaelic football tournament for the Gaelic Athletic Association county teams of Ireland.
Kerry beat Mayo in the final.
Each team played every other team in its division (or group where the division is split) once, either home or away.
2 points were awarded for a win and 1 for a draw.
In the event that teams finish on equal points, then a play-off will be used to determine group placings if necessary, i.e. where to decide relegation places or quarter-finalists.
