1963–64 National Football League (Ireland)

The 1963–64 National Football League was the 33rd staging of the National Football League (NFL), an annual Gaelic football tournament for the Gaelic Athletic Association county teams of Ireland.

New York again got a bye to the final. Dublin met them after a win over Down in the Home Final, and travelled to The Bronx for the final, also billed as the "World Championship". A Brendan O'Donnell goal after half-time allowed NY to build up a seven-point lead, which a Dublin rally reduced to one point. Late in the game, players brawled on the field and were joined by a spectator, who received a black eye. New York captain Tom Hennessy scored a late point to seal victory.
