The Catholic Church in Switzerland (German: Römisch-katholische Landeskirche, French: Église catholique en Suisse, Italian: Chiesa cattolica in Svizzera, Romansh: Baselgia catolica da la Svizra) is organised into six dioceses and two territorial abbeys, comprising approximately 2.7 million Catholics, about 30.7%[1] of the Swiss population in 2023.

In the last thirty years, mainly during the conflict over the appointment of Wolfgang Haas as Bishop of Chur, there have been discussions to make a major reform of the structure of the Catholic Church in Switzerland, which would probably also lead to the establishment of a metropolitan see (probably in Lucerne).

The status of Catholicism in Switzerland is complicated further by the existence of Landeskirchen (Catholic cantonal churches), imposed by anti-clerical cantonal governments in the 19th century and organised along democratic lines and control the application of funds collected through church taxes.

Most cantonally delineated Catholic church bodies are members in their umbrella Roman Catholic Central Conference of Switzerland (RKZ, official names in German: Römisch-Katholische Zentralkonferenz der Schweiz, French: Conférence centrale catholique romaine de Suisse, Italian: Conferenza centrale cattolica romana della Svizzera, Romansh: Conferenza centrala catolica romana da la Svizra).

Currently, there are two living Cardinal from Switzerland, Kurt Koch and Emil Paul Tscherrig.
