The 1942–43 Gauliga was the tenth season of the Gauliga, the first tier of the football league system in Germany from 1933 to 1945. It was the fourth season of the league held during the Second World War.

The league operated in twenty-nine regional divisions, four more than in the previous season, with the league containing 298 clubs all up, 33 more than the previous season. The league champions entered the 1943 German football championship, won by Dresdner SC who defeated FV Saarbrücken 3–0 in the final. It was Dresden's first national championship and the club would go on to win the competition in the following season as well.^[1]

The 1942–43 season saw the ninth edition of the Tschammerpokal, now the DFB-Pokal.
