The Association of Catholic Nobles in Austria was an organization of Austrian nobles. Founded shortly before the start of World War I, it did not begin its activities until 1922. The association was banned by the National Socialists following the occupation of Austria.

According to its bylaws, its purpose was, among other things, to foster a noble spirit and to promote Catholic beliefs. Furthermore, one of its objectives was to create a registry of families entitled to bear a noble title until the Austrian Abolition of the Nobility Act of 1919 came into effect, as well as to support members in financially difficult circumstances.

As an unofficial successor organization to the Association of Catholic Nobles in Austria, the St. Johanns Club was founded in 1954 under the patronage of the Order of Malta. However, this club cannot be regarded as a noble association, as it also includes non-noble members.
