Národní Liga — National League —, or Česko-moravská liga — Bohemian-Moravian League —, was the main league played in Bohemia and Moravia during Nazi Germany's occupation of the territory. In the middle of the 1938/39 season, after another normal start, the troops of Nazi Germany acquired the Protectorate of Bohemia and Moravia, therefore creating a new league completely different from the old Státní Liga.

The league was specifically known for a high number of goals per match, teams with a very open style of play and careless with the defensive system. However, it followed with both top teams — S.K. Slavia Praha & A.C. Sparta Praha — dominating the competition by strides. Furthermore, already in the middle of the 1938/39 season, the Slovakian teams that were inserted after the 1935/36 season were removed from the competition system, therefore, in 1938/39, Š.K. Bratislava had its results annulled.

Even before the 1944/45 edition was contested, Czechoslovakia's wartime situation worsened. Consequently, there was no official edition in 1944/45. The league was only reestablished in 1945/46.
