The 1975 Rugby League World Championship (also referred to as the World Series) was the seventh ever tournament for the Rugby League World Cup. The format differed radically from that employed in previous competitions; no one 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.
