Wigan won their sixth Championship when they beat Dewsbury 13-4 in the play-off final at Maine Road, Manchester in front of a crowd of 40,599. Wigan scored three tries and two goals to Dewsbury's two goals. Wigan had also ended the regular season as league leaders.
Leeds reached the Wembley final for the second time, doing so without conceding a single point in the final five rounds of the tournament. However Bradford Northern beat Leeds 8-4 in the final in front of a crowd of 77,605. Trevor Foster and Emlyn Walters scored Bradford's tries and were converted by Ernest Ward. Willie Davies, Bradford Northern's stand-off half back, won the Lance Todd Trophy for man of the match.
This was Bradford’s third Cup Final win in five Final appearances including one win and one loss during World War II.
