The 1975 Rugby League World Championship was the seventh tournament for the Rugby League World Cup. The format differed from that employed in previous competitions; no single country hosted the matches, which were spread out in a 'world series' hosted by each of the five participating nations over a period of just over eight months. Each team had to play the others on a 'home and away' basis. Great Britain were split up into separate England and Wales teams, taking advantage of a glut of Welsh talent in the British game at the time.
