St Columb Minor is in the Deanery and Hundred of Pydar. It is bounded on the North by Mawgan-in-Pydar, on the East by St Columb Major and Colan, on the South by Newlyn East, and on the West by the Bristol Channel. A large area of North Cornwall bears the name of St Columb; it is divided between the parishes of St Columb Major and St Columb Minor. Until relatively recently these were known as Higher and Lower St Columb. Another old name used for St Columb Minor was Nether St Columb. In 1960, the civil parish of St Columb was subsumed by Newquay of which St Columb Minor is now a suburb. Villages in this parish were: Trencreek, Chapel Porth, Lane, Shop, Trenance and the Churchtown.
