A Tory () is a person who holds a political philosophy known as Toryism, based on a British version of traditionalism and conservatism, which upholds social order as it has evolved in the English culture throughout history. The Tory ethos has been summed up with the phrase "God, King, and Country". Tories are monarchists, were historically of a high church Anglican religious heritage, and opposed to the liberalism of the Whig faction.

The philosophy originates from the Cavalier faction, a royalist group during the English Civil War. The Tories political faction that emerged in 1681 was a reaction to the Whig-controlled Parliaments that succeeded the Cavalier Parliament. As a political term, Tory was an insult derived from the Irish language, that later entered English politics during the Exclusion Crisis of 1678–1681.

It also has exponents in other parts of the former British Empire, such as the Loyalists of British America, who opposed US secession during the American War of Independence. The Loyalists who fled to the Canadas at the end of the American Revolution, the United Empire Loyalists, formed the support base for political cliques in Upper and Lower Canada.

Toryism remains prominent in Canada and the United Kingdom. The British Conservative Party and Conservative Party of Canada, and their members, continue to be referred to as Tories. Adherents to traditional Toryism in contemporary times are referred to as High Tories, who typically defend the ideas of hierarchy, natural order, and aristocracy.
