Dornoch Cathedral is a Church of Scotland parish church serving the small Sutherland town of Dornoch, in the Scottish Highlands. As a congregation of the Church of Scotland, which is Presbyterian, the church is not the seat of a bishop but retains the name due to being, historically, the seat of the Bishop of Caithness. The cathedral's churchyard is adjoined by Dornoch Castle, the somewhat reconstructed remains of the medieval palace of the Bishops of Caithness. It was formerly a Catholic Cathedral.

Dornoch is a town, seaside resort, parish and former royal burgh in the county of Sutherland in the Highlands of Scotland. It lies on the north shore of the Dornoch Firth, near to where it opens into the Moray Firth to the east.
