Roman Catholic bishop of Argyll and the Isles

The Bishop of Argyll and the Isles is the ordinary of the Roman Catholic Diocese of Argyll and the Isles in the Province of Saint Andrews and Edinburgh, Scotland.

The Scottish hierarchy was restored by Pope Leo XIII on 15 March 1878 and the ancient bishoprics of Argyll and the Isles were re-established and united under one bishop. The diocese covers an area of 31080 km2 and comprises most of Argyll and Bute, the southern part of the Highland council area, the Outer Hebrides, and the Isle of Arran. The Episcopal see is in the town of Oban where the bishop's seat is located at the Cathedral Church of St. Columba.

On 28 December 2015 Pope Francis appointed Monsignor Brian McGee as bishop.
