The Reverend Thomas Seaton (baptised 2 October 1684, Stamford, Lincolnshire, died 18 August 1741 at Ravenstone, Buckinghamshire), was a Church of England clergyman and religious writer.
He was educated at Stamford School and Clare College, Cambridge, graduating a BA in 1705 and a MA in 1708.
In 1713, he gained the vicarage of Madingley, Cambridgeshire, and in 1721 the city of Nottingham gave him the vicarage of Ravenstone in Buckinghamshire, which enabled him to give up his college fellowship with which he retained until his death.
On his death, Seaton left his estate at Kislingbury, Northamptonshire, to the University of Cambridge, with the object of funding an annual poetry prize for a poem in English on the nature of God or on another sacred subject, the judges to be the university's Vice-chancellor, the Professor of Greek, and the Master of Clare College.
George Gordon, Lord Byron, another Cambridge graduate, refers to recipients of the celebrated university prize as "Seaton's sons" in his poem English Bards and Scotch Reviewers (1809).
