Robert Cary (1615?–1688) was an English churchman, for a short while archdeacon of Exeter, known as a chronologist.
His kinsman, William Seymour, Marquess of Hertford, who was chancellor of the university, obtained for him the degree of D.C.L.
He gave up his preferment, feeling threatened by 'some great men then in power' in 1664, and retired to his rectory, where he lived quietly till his death, on 19 September 1688.
John Milner of Cambridge, published, in 1694, a Defence of Archbishop Ussher against Dr. Robert Cary and M. Is.
Cary also translated some hymns from the church services into Latin verse, and printed them on folio sheets.
