±Benjamin Chetwood (1655 - 1728) was an Irish politician of English birth. Chetwood sat in the Irish House of Commons as the Member of Parliament for Harristown between 1713 and 1714. He was the fourth son of Valentine Chetwood of Chetwood, Buckinghamshire and Mary Shute, daughter of Francis Shute of Upton, Leicestershire. Knightly Chetwood, Dean of Gloucester, was his elder brother. Precisely when he came to Ireland is unclear. He married Anne Eustace, daughter of Sir Maurice Eustace (died 1703) of Harristown, County Kildare and Eustace Street, Dublin and his first wife Anne Colville, by whom he had at least seven children, including Chetwood, the eldest son and heir. She died in 1713.
