Rev. Ralph Levett (1600 - ca. 1660) was an Anglican minister who served as domestic chaplain to an aristocratic English family from Lincolnshire with Puritan sympathies, who subsequently installed him as rector of the local parish. A graduate of Christ's College, Cambridge, where he became a protégé of the prominent Puritan minister John Cotton, Levett later married the sister of the wife of his friend Rev. John Wheelwright, another well-known early Puritan settler of New England.
