The Roman Catholic Archdiocese of Paraná (Latin: Archidioecesis Paranensis) is a metropolitan diocese.

Its suffragan sees include Concordia and Gualeguaychú.

The Diocese of Paraná was elevated to an archdiocese by Pope Pius XI on 20 April 1934.

It lost territory two more times when the dioceses of Gualeguaychú (1957) and Concordia (1961) were created.
