The Roman Catholic Church in Poland comprises mainly sixteen Latin ecclesiastical provinces, each headed by a metropolitan, whose archdioceses have a total of 28 suffragan dioceses, each headed by a bishop. They are all members of the Episcopal Conference of Poland, one of the larger conferences in Europe, slightly smaller than Spain, but larger than the United Kingdom or Germany and by far the most established conference in all of Eastern Europe.

Furthermore, there are

• an exempt military ordinariate for the armed forces
• the Eastern Catholic province of the Metropolitan Ukrainian Catholic Archeparchy of Przemyśl–Warszawa and its suffragans as a Byzantine Rite in Ukrainian language
• an Ordinariate for the Faithful of the Eastern Rites for all other non-Latin rites in Poland.

There is also an Apostolic Nunciature to Poland, as papal diplomatic (embassy-level) representation.
