The diocese of Molfetta-Ruvo-Giovinazzo-Terlizzi (Latin: Dioecesis Melphictensis-Rubensis-Iuvenacensis-Terlitiensis) is a Roman Catholic ecclesiastical territory in Apulia, southern Italy, which was established in 1986, when the diocese of Molfetta-Giovinazzo-Terlizzi was united with the diocese of Ruvo. Giovinazzo is only four miles south-east of Molfetta along the Adriatic coast, and Ruvo only ten miles inland to the south-west; Terlizzi is likewise only four miles from Molfetta, some four miles nearer than Ruvo. The historical diocese of Molfetta was expanded in 1818. The current diocese is a suffragan of the archdiocese of Bari-Bitonto.
The first bishop of Molfetta of whom there is any record was John, whose incumbency is referred to the year 1136. The see was at first suffragan of Bari, but in 1484 it became immediately dependent upon Rome. In 1818, it was enlarged with the territory of the suppressed diocese of Giovinazzo and diocese of Terlizzi, which were re-established in 1835, remaining united, aeque principaliter.Pope Innocent VIII (Cibo) granted the diocese the privilege of being immediately subject to the Roman pontiff, without any other Metropolitan.
In 1600 the city of Molfetta had a population of around 10,000; in 1775 it was around 9,000. In the city were five religious houses for men, and one monastery of male monks. In 1775 there were four religious houses.Under Bishop Simon Alopa the number of Canons in the Cathedral Chapter was fixed at twenty-four, reducing the number from thirty-six. In addition to the Canons there were six dignities in the Chapter, the Archdeacon, the Archpriest, two Primicerii (Cantores), the Penitentiary and the Sacristan. The current Chapter preserves these six dignities, but there are only eleven Canons and two Honorary Canons.
