The 1945 Republic Football Championship was a national football competition in Bulgaria. From 1945 to 1948, the Bulgarian Republic Football Championship was the successor of the Bulgarian State Football Championship.
The 1945 season was contested by 24 teams, and Lokomotiv Sofia won the championship. As Bulgaria had lost the territories of Vardar Macedonia, Western Thrace and parts of Greek Macedonia that it administered during most of World War II, teams from those regions no longer took part in the Bulgarian championships, beginning in 1945.
