List of Catholic dioceses in Germany between 1821 and 1993

This list refers to the Roman Catholic dioceses and ecclesiastical provinces in Germany and the organisational changes between 1821 and 1994. The territorial changes through and after the Napoleonic Wars determined much of today's diocesan boundaries. The territorial changes after the World Wars were followed by new diocesan boundaries in the 1920s and 1970s. Internal reorganisations took place in the 1930s, 1950s and early 1990s.

The reorganisation of the Roman Catholic dioceses in Germany after 1818: Pre-Napoleonic diocesan borders as black lines, new diocesan areas as different-coloured fields, episcopal sees by 1824 as red spots.
