This is a list of Cornish saints, including saints more loosely associated with Cornwall: many of them will have links to sites elsewhere in regions with significant ancient British history, such as Wales, Brittany or Devon.

List of some of the well-known Cornish saints

For more information see the works of Canon Doble (1880–1945), Nicholas Orme's book, The Saints of Cornwall (2000), and the works of Charles Henderson N.B. All these have dedications in Cornwall but not all have legends or traditions associating them with Cornwall.
