The 2013 Nigeria Professional Football League was the 42nd season of the competition since its inception, and the 23rd since the rebranding of the league as the "Professional League". Due to start in December, numerous delays and challenges to the board pushed the opening weekend back to February, and then pushed to March 9. There was a season-opening Super Four tournament, won by Heartland F.C., between the four clubs involved in Continental competitions in order to get them ready for their international assignments.
