Bishop of Dunkeld
The Bishop of Dunkeld is the ecclesiastical head of the Diocese of Dunkeld, one of the largest and more important of Scotland's 13 medieval bishoprics, whose first recorded bishop is an early 12th-century cleric named Cormac. However, the first known abbot dates to the 10th century, and it is often assumed that in Scotland in the period before the 12th century, the roles of both bishop and abbot were one and the same. The Bishopric of Dunkeld ceased to exist as a Catholic institution after the Scottish Reformation but continued as a royal institution into the 17th century. The diocese was restored by Pope Leo XIII on 4 March 1878; it is now based in the city of Dundee.
List of known abbots
Dunkeld Abbey was an offshoot of Iona, perhaps founded in the early 9th century, in the reign of Caustantín mac Fergusa, King of the Picts. It is not clear when its abbots got independence from the Abbots of Iona, but a notable event is the alleged transfer of the relics of Columba to Dunkeld during the reign of the Scoto-Pictish king Cináed mac Ailpín. Its abbots, like many Gaelic abbots of the period, took a strong role in secular affairs, hence the term "lay abbot". The following is a list of known abbots of Dunkeld; the list is not exhaustive.| Tenure | Incumbent | Notes |
| d. 865 | Túathal of Dunkeld | The Annals of Ulster, s.a. 865.6, records his obit and writes "Tuathal m. Artgusso prim-epscop Fortrenn & abbas Duin Caillenn", that is, "Túathal son of Artgus, chief bishop of Fortriu and Abbot of Dunkeld ". |
| d. 873 | Flaithbertach of Dunkeld | The Annals of Ulster, s.a. 873.8, records his obit and writes "Flaithbertach m. Muirchertaigh, princeps Duin Chaillden, obiit", that is, "Flaithbertach son of Muirchertach, superior of Dún Caillen, died". |
| d. 965 | Dúnchad of Dunkeld | Dúnchad was killed along with Dubdon, Mormaer of Atholl in the battle of dorsum Crup, fought between king Dub and king Cuilén. |

While it is true that medieval churchmen took an active part in secular affairs, that didn't make them in any sense "lay." They were still consecrated bishops or abbots. A "lay abbot" was the secular lord of the abbey's lands. Since an abbey's property was often extensive, it was lucrative plum. Medieval monarchs enjoyed considerable authority over the church, and doubtless, these positions were awarded to royal favorites.
