Priest Cove (Cornish: Porth Ust, meaning St Just's Cove) or Priest’s Cove is a small cove one mile (1.6 km) west of St Just, Cornwall, UK. The name is from the Cornish Porth Ust, the port or cove of St Just, which was shortened to Por’ Ust. The cove lies next to Cape Cornwall which was also linked to St Just, being called Kilgoodh Ust, meaning goose-back of St Just, in the Cornish language. "Priest’s" is a spelling mistake on the Ordnance Survey and there is no connection with the clergy. The cove and surrounding area is designated as part of the Aire Point To Carrick Du Site of Special Scientific Interest (SSSI).
