Leonard Smelt (c. 1683 – 30 May 1740) of Kirkby Fleetham, North Riding of Yorkshire, was an English Whig politician who sat in the House of Commons between 1709 and 1740.
[2] In 1709, in an unopposed by-election on 6 May for Thirsk, Smelt became the first person in his family to be an MP.
He supported the Whig government and was appointed commissioner for army debts in 1715.
He was returned unopposed again at the 1722 British general election and was appointed clerk of deliveries at the Board of Ordnance in 1722.
