The 1st Belorussian Front (alternative spellings are 1st Byelorussian Front and 1st Belarusian Front) was a military subdivision (Front) of the Soviet Army during the Second World War. This sense of the term is not identical with the more general usage of military front which indicates a geographic area in wartime, although a Soviet Front may operate within designated boundaries. Its subordinate formations included the 8th Guards Army.
