The 1972–73 Northern Rugby Football League season was the 78th season of rugby league football played in England. It would also be the last season whereby the British championship was decided by a play-off system until Super League III in 1998. Dewsbury were crowned champions after defeating Leeds in the Final. The 1972–73 season was also punctuated by the 1972 Rugby League World Cup which was played in France in October and November. At the end of this season the league re-formed into two divisions. The top 16 in the championship would form Division 1 and the bottom 14 Division 2.
