The 1938 WANFL season was the 54th season of the Western Australian National Football League, and saw Claremont, under champion coach Johnny Leonard who had transferred from West Perth, win its first premiership after losing two Grand Finals and drawing the first one this season. The blue and golds were to win the following two premierships before a long period near the foot of the ladder after Claremont Oval was gutted by a fire in 1944.
