This article gives a list of the territories of the dioceses of the Catholic Church in India.

Each diocese is administered by a bishop. Dioceses are further grouped into ecclesiastical provinces. The most important diocese of the province is the archdiocese, and the bishop of this diocese is an archbishop. While they each usually consist of a few Indian civil districts, dioceses can range in size from just a portion of a district to spanning entire states. The civil district should not be confused with ecclesiastical district or deanery, which is another type of subdivision of a diocese.

All Catholics in India are under the authority of the respective Syro-Malankara, Syro-Malabar, or Latin bishop (personal jurisdiction). Only in the areas of the Syro-Malabar dioceses of Adilabad, Bijnor, Chanda, Gorakhpur, Jagdalpur, Rajkot, Sagar, Satna, and Ujjain, not covered by Latin rite dioceses, the authority of the Syro-Malabar bishop is over both Syro-Malabar and Latin rite Catholics.

It is to be noted that the territory of the Kingdom of Bhutan completely falls under the territorial jurisdiction of the Bishop of Darjeeling.

In the following, the names listed after the name of the state or union territory are the names of civil districts, unless otherwise mentioned. Some newly-created districts may be missing from this list.
