This is a list of cathedrals in Austria, including both actual and former diocesan cathedrals (seats of bishops). Almost all cathedrals in Austria are Roman Catholic, but any non-Roman Catholic cathedrals are also listed here.

The list is intended to be complete.

Although the word "Kathedrale" is used formally in German, the more usual word is "Dom". This not only refers to cathedrals in the proper sense as the seats of bishops, but also to a small number of large churches in Austria, which are known as "Dom" as a mark of distinction or historical importance (sometimes known by the description "Prachtdom", i.e., churches called "Dom" because of their magnificence or splendour). These are included in a separate section, without implying that they have the status of cathedrals.
