The 1925 WAFL season was the 41st season of the West Australian Football League. It was notable as the season where a fully-fledged system of district football was firmly in place after two seasons of planning, with Perth divided into eight zones, one of which was allocated to Claremont in preparation for their entry to senior WAFL ranks for 1926 and another covered the Midland area later to be allocated to Swan Districts. Along with this, the WAFL introduced a reserves competition for players not good enough for their club's league team.
