The 1938 season of the Peruvian Primera División, the top category of Peruvian football, was played by 9 teams. The national champions were Deportivo Municipal.[1][2] Because Alianza Lima and Sucre tied on points a relegation playoff took place.[3] From 1931 until 1942 the points system was W:3, D:2, L:1, walkover:0.
