Thomas Bennett (c. 1674–1738) of Welby, Leicestershire, was a British Whig politician who sat in the House of Commons from 1732 to 1738.
[2] Bennett was invited by the Duke of Newcastle to sit as Member of Parliament for Nottinghamshire as a stop-gap, keeping the seat warm for Lord Howe who had been appointed Governor of Barbados.
In 1733 he tried, on Newcastle's behalf, to persuade the Duke of Kingston to accept a place as Lord of the bedchamber.
Bennett was returned unopposed again for Nottinghamshire at the 1734 British general election, despite some local discontent because he was a Leicestershire man.
In the autumn of 1737 Bennett fell ill of a dropsy and died unmarried on 10 June 1738.
