The Archdeacon of St Davids is a senior cleric in the Church in Wales' Diocese of St Davids. The archdeacon is the senior priest with responsibility over the area of the archdeaconry of St Davids, one of three archdeaconries in the diocese (the others are Cardigan and Carmarthen). The Archdeaconry of St Davids comprises the four rural deaneries of Daugleddau, Dewisland/Fishguard, Pembroke and Roose.^[1]

The first recorded archdeacons of St Davids occur soon after the Norman Conquest. However, no territorial titles are recorded until after c. 1125.
