The Bishop of Down and Connor () is an episcopal title which takes its name from the town of Downpatrick (located in County Down) and the village of Connor (located in County Antrim) in Northern Ireland. The title is still used by the Catholic Church for the diocese of that name, but in the Church of Ireland it has been modified into other bishoprics.

History The sees of Down and Connor were established at the Synod of Rathbreasail in 1111. For a brief period in the early 12th century, they were united under Máel Máedóc Ua Morgair (Saint Malachy), who also became Archbishop of Armagh., Handbook of British Chronology, pp. 334, 343 and 347.

On 29 July 1438, plans for a permanent union of the sees of Down and Connor were submitted to King Henry VI of England for his sanction., Handbook of British Chronology, pp. 344 and 348. Exactly twelve months later, 29 July 1439, Pope Eugene IV issued a papal bull stating that Down and Connor were to be united on the death or resignation of either bishop. In 1442, Bishop John Sely of Down was deprived of his see by Pope Eugene IV,Kilclief Castle. Irish Antiquities. Retrieved 25 August 2009.Kilclief Castle, County of Down. Library Ireland.

However, due to strong opposition to the union in the diocese of Down, three more bishops of Down were appointed, two whilst Fossade was alive and one after his death. It was not until the appointment of Thomas Knight that the two sees accepted union under one bishop.

Following the upheaval of the 16th-century Reformation in Ireland, there were parallel apostolic successions. In the Church of Ireland, Down and Connor merged with Dromore in 1842 to form the Bishopric of Down, Connor and Dromore. This arrangement continued until 1945 when it was separated into the bishoprics of Down & Dromore and Connor., Handbook of British Chronology, pp. 388–389., The Province of Connaught, pp. 202–218.

In the Roman Catholic Church, the see of Down and Connor continues. Since the first half of the nineteenth century the bishop has lived in Belfast rather than the Downpatrick area. The incumbent is the Most Reverend Alan McGuckian, Bishop of the Roman Catholic Diocese of Down and Connor, who was appointed by the Holy See on 2 February 2024 and ordained bishop on 6 August 2017.Bishops of Down and Connor.
