Herzegovina Affair (Croatian: Hercegovačka afera) or Herzegovina Case (Croatian: Hercegovački slučaj) refers to a conflict between the Franciscan Province of Herzegovina and the Diocese of Mostar-Duvno over the redistribution of parishes in the said diocese. The conflict between the Franciscans and the diocesan clergy started with the restoration of the regular church hierarchy in Bosnia and Herzegovina after its occupation by Austria-Hungary in 1881. The Herzegovina Case presents a problem in the relationship between the Herzegovinian clergy, as well as the Catholic faithful.
