Tetton is an historic estate in the parish of Kingston St Mary in the English county of Somerset.
The present grade II* listed Tetton House dates from 1790 and was enlarged and mainly rebuilt in 1924–6 by Hon.
Sir John Acland, 1st Baronet (c. 1591 – 1647) moved his residence from Acland to Columb John, near Exeter, the former seat of his great-uncle Sir John Acland (died 1620), and soon after the family moved again to the adjoining estate of Killerton where they built a grand country house, today the property of the National Trust.
In the late 19th century the gate piers and walls from Tetton were moved to Cothelstone Manor.
