Sir John Bennet (1553 – 15 February 1627) was a judge and politician who sat in the House of Commons between 1597 and 1621. His career ended in disgrace after he was found guilty of extorting bribes and excessive fees.
Bennet was the second son of Richard Bennet of Clapcot, Berkshire (now in Oxfordshire) and his wife, Elizabeth Tesdale, the daughter of Thomas Tesdale of Stanford Dingley and Abingdon. She was the half-sister of Thomas Tesdale, the founder of Pembroke College, Oxford. He was probably educated at Abingdon School of which his family were benefactors. He matriculated at Christ Church, Oxford in 1573. He was awarded BA in 1577 on 11 June 1577 and his MA on 15 June 1580. In 1583 he was incorporated at Cambridge and awarded MA there. He returned to Oxford and was elected a proctor in 1585. He was awarded his BCL and DCL by special dispensation on 6 July 1589. In the following year was admitted as an advocate in the Court of Arches.
Bennet began his career as vicar-general and chancellor in the Diocese of York, probably through the influence of John Piers, the Archbishop of York, who had been the Dean of Christ Church. He was joint commissary of the exchequer court. In 1591 he was appointed to the prebend of Langtoft. In 1594 he was appointed J.P. for the East Riding of Yorkshire. He advanced his career in other areas, serving as a legal adviser to a commission negotiating with Scotland about the security of the border, and in 1599 was appointed to the Council of the North.
