The Metropolitan Archdiocese of Warsaw (Latin: Archidioecesis Metropolitae Varsaviensis, Polish: Archidiecezja Metropolita Warszawska) is a Latin Church ecclesiastical territory or diocese of the Catholic Church in Poland encompassing the Polish capital.

According to the archdiocese's statistics, 30.4% of its population attended a church weekly in 2013.

That is higher than a year earlier (29.8%) but church attendance may still be declining.

The current archbishop, Kazimierz Nycz, formerly Bishop of Koszalin-Kolobrzeg, Poland, was named on 3 March 2007.

Following the abrupt resignation of Archbishop Stanisław Wielgus in January, Józef Cardinal Glemp had been named its Apostolic Administrator.
