Arthur Moore M.P. (ca.1660 – 4 May 1730) was an Irish businessman, economist and politician. He was Member of Parliament for Great Grimsby for many years.
He was said to have been born in Monaghan, about 1666. An adventurer, his background was said to have been in service.
Moore studied trade questions, made money rapidly, and in 1695 was returned to parliament for the borough of Great Grimsby, in Lincolnshire. At the election of February 1700-1 general bribery prevailed there, and although Moore petitioned against the members returned he did not claim the seat, and bribery was proved in his interest. With the exception of that short parliament, he represented the borough from 1695 to 1715, and he was again elected on a by-vacancy in February 1721. In October 1722 he petitioned for the seat, but withdrew his claim next month. He had a house in Grimsby, and was high steward of the borough from 1714 to 1730.
Moore's name appeared in 1702 among the managers of the "united trade to the East Indies". He was a director of the South Sea Company, and was appointed comptroller of the army accounts in 1704. It was reported on 15 April 1701 that he was about to be added to George, Prince of Denmark's council on admiralty affairs. On 30 September 1710 he was made one of the lords commissioners of trade and plantations; he held this post during the remainder of the reign.
During the last years of Queen Anne he showed great skill in parliament, and was deemed highly capable. His brother Thomas Moore was made paymaster of the land forces abroad in August 1713. Moore mediated between Robert Harley, 1st Earl of Oxford and Henry St John, 1st Viscount Bolingbroke in their quarrels, but threw in his lot with the latter. In later years he supported Robert Walpole.
The articles of the treaties with France and Spain (1712) which related to commerce were mainly drawn up by Moore. He was responsible for free trade clauses, eventually cancelled. They brought him hostility from Whigs in the City of London. A Whig attack on Bolingbroke through Moore, corruption and the treaties backfired on Robert Monckton and Harley when he brought it up.
