Thomas Potter (1718–1759) was a British politician who sat as a Member of Parliament for Aylesbury, Okehampton and St Germans in Cornwall.
Potter was the second son of John Potter, Archbishop of Canterbury. He was born in 1718. He acquired a law degree at Christ Church, Oxford, and was admitted to the Middle Temple. Through his father's interest, he was able to secure the Recordership of Bath, a lucrative office. Originally a member for St Germans, in 1754 he was elected as MP for Aylesbury, a seat controlled by the powerful Grenville family with whom he was associated from then on. In 1756 he became a Vice-Treasurer of Ireland, another lucrative post, which did not require him to move to Ireland.
Potter acquired a reputation as a leading rake. Potter was a friend of John Wilkes, who he considered as something of a protégé. He was later accused of corrupting Wilkes who had been relatively innocent until that point. Politically he was aligned with William Pitt who he was a devoted follower of. He was a staunch supporter of Britain's participation in the Seven Years War.
