Thomas Webb (c. 1663 – 26 March 1734), of Gloucester, was an English merchant and Tory politician who sat in the House of Commons from 1708 to 1713.
He was a very inactive Member in the House, presumably because he was involved in supporting the Tories in local affairs for which he was deemed indispensable.
On the appointment of the Tory ministry he applied to Harley to be restored to his post as receiver-general, which had been taken from him by the Whigs, but to no avail.
He was returned for Gloucester at the 1710 British general election with the support of Dr Knightly Chetwood, dean of the city, and the Duke of Beaufort.
The allegation was probably Whig ploy to disrupt the Tories’ electoral arrangements, since it was said that the general understanding was that ‘no receiver in England hath made better payments than Alderman Webb'.
