The Diocese of Minsk (Russian: Минская епархия; Belarusian: Мінская епархія) is an eparchy of the Belarusian Orthodox Church, which is an exarchate of the Russian Orthodox Church.

It was established for the regions, which became part of the Russian Empire at the second partition of Poland, instead of Turov diocese, remained until 1798 in the conduct of the Kiev Metropolitanate, and also the bishoprics in Slutsk, formerly frontiers of the Kingdom of Poland.

Initially, the Department was located in Slutsk, was moved to Minsk by decree on 12 April 1795, but according to Stepan Runkevich, in fact, it moved to Minsk only on 3 September 1799.

Thus it became extremely large, and the reunion with the Orthodox Church of one and a half million Western Russian Uniates made it even larger.

In the second half of the Soviet period, it occupied the territory of the entire Byelorussian SSR.
