St Dominic is a rural parish in east Cornwall, sandwiched between the river Tamar and the A388 between Callington and Saltash. Much of the land is used for agriculture, market gardening and horticulture, and in the eighteenth and nineteenth centuries there was also some mining activity.
The main village is St Dominic, which has a school, pub, post office and shop. The 13th century parish church, dedicated to St Dominica, lies at the western end of the village. There are smaller settlements at Bohetherick, Burraton, Halton Quay and Ashton. Halton and Ashton are both mentioned in the Domesday Survey.
A small chapel at Halton Quay marks the supposed landing of St Dominica and her brother St Indract of Ireland in the 7th Century.
Cotehele Mill, part of the National Trust Cotehele Estate, lies just in the parish. This 19th century water mill has been restored and now grinds wholemeal flour.
