Port Eliot in the parish of St Germans, Cornwall, England, United Kingdom, is the ancestral seat of the Eliot family, whose present head is Albert Eliot, 11th Earl of St Germans.
Port Eliot comprises a stately home with its own church, which serves as the parish church of St Germans. An earlier church building was Cornwall's principal cathedral. The house is within an estate of 6,000-acre which extends into the neighbouring villages of Tideford, Trerulefoot and Polbathic. Both house and garden are Grade I listed.
