The Bishop of Raphoe is an episcopal title which takes its name after the town of Raphoe in County Donegal, Ireland. In the Roman Catholic Church it remains a separate title, but in the Church of Ireland it has been united with another bishopric.

In the earliest period of the diocese, the episcopal see was often referred to as Tír Conaill (the surrounding region). It was also sometimes written as Ráith Both, the Middle Irish spelling of the location. In 1266, Bishop Germanus of Derry forcibly transferred the Inishowen peninsula from jurisdiction of the diocese of Raphoe to Derry.
After the Reformation, there were parallel episcopal successions. In the Church of Ireland, the title continued until 1834 when it united with Derry and formed the united bishopric of Derry and Raphoe.
In the Roman Catholic Church, the title continues as a separate bishopric. The current Incumbent is the Most Reverend Philip Boyce, O.C.D., Bishop of the Roman Catholic Diocese of Raphoe, who was appointed by Pope John Paul II on 29 June 1995 and received episcopal ordination on 1 October 1995.
