Samuel Smith (14 April 1754 – 12 March 1834) was a British Tory Member of Parliament and banker.
Samuel Smith the fourth son of Abel Smith, a wealthy Nottingham banker and Member of Parliament. Four of his brothers were also Members of Parliament and one, Robert, was raised to the peerage as Baron Carrington. A portion of the family wealth was devoted to buying control of two pocket boroughs, Wendover and Midhurst, and Carrington kept the seats here almost exclusively for use by various members of the Smith family until his power was ended by the Great Reform Act.
Smith entered Parliament in 1788 as member for St Germans, and was an MP for the next 44 years, also representing Leicester (1790–1818), Midhurst (1818–1820) and Wendover (1820–1832). He and his son Abel were Wendover's last MPs, as they sat together as its members for the last two years before the borough's abolition. In 1826, being the longest continually-serving MP, he became Father of the House. He did not return to Parliament after the 1832 Great Reform Act, dying two years later.
In 1801 Smith bought Woodhall Park in Hertfordshire, which still belongs to his descendents.
Smith married Elizabeth Turnor on 2 December 1783. They had seven daughters and four sons. As well as his son Abel, his grandson Samuel George Smith was a Member of Parliament.
