The Diocese of Ross was an ecclesiastical territory or diocese in the Highland region of Scotland during the Middle Ages and Early modern period. The Diocese was led by the Bishop of Ross, and the cathedral was, latterly, at Fortrose. The bishops of the Early Church were located at Rosemarkie. The diocese had only one Archdeacon, the Archdeacon of Ross, first attested in 1223 with the appearance of Archdeacon Robert, who was consecrated bishop of Ross on 21 June 1249 x 20 June 1250.[clarification needed] There is only one known Dean of Christianty (sic) (rural dean), one Donald Reid called the dean of christianty of Dingwall on 12 June 1530.
A dean of the cathedral chapter (Henry) is first recorded in 1212 x 1213; a Subdean (William de Balvin) in 1356. A Precentor, sometimes in Scotland called Chanter, (Adam de Darlington) is attested in 1255, a Succentor (Matthew) in 1255. A Chancellor (Maurice) is attested for the first time in 1212 x 1213, a Treasurer (William) in 1227.
In the twelfth century, the diocese is usually called "Rosemarkie", but thereafter it is called Ross. The diocese covered, roughly, the old county of Ross (also called Ross-shire).
