The Roman Catholic Church in Belarus, united in the Episcopal Conference of Belarus, a Slavic ex-Soviet country in Eastern Europe, is presently only composed of one Latin ecclesiastical province, comprising the Metropolitan of Minsk-Mohilev and his three Suffragan dioceses.
There are no Eastern Catholic dioceses (or eparchies) but there is an apostolic administrator for the Belarusian Greek Catholic Church.
There is an Apostolic Nunciature to Belarus as papal diplomatic representation (embassy-level) in the national capital Minsk.
