The Catholic Church in Russia, united in the Episcopal Conference of Russia, comprises one Latin ecclesiastical province (the Metropolitan archdiocese of Moscow, with three Suffragan dioceses) and a missionary (hence exempt) apostolic prefecture. The Eastern Catholics have two proper jurisdictions, each belonging to a different particular church sui iuris and using a different rite.
There are no exempt Latin jurisdictions.
There is an Apostolic Nunciature as papal diplomatic representation (embassy-level) to the Russian Federation in the national capital Moscow.
