The Adam Smith Institute (ASI) is a UK-based neoliberal think tank and lobbying group, named after Adam Smith, a Scottish moral philosopher and classical economist. The Institute advocates free market and classical liberal ideas, primarily via the formation of policy options with regard to public choice theory, which political decision makers seek to develop upon. ASI President Madsen Pirie has sought to describe the activity of the organisation as "[w]e propose things which people regard as being on the edge of lunacy. The next thing you know, they're on the edge of policy".

Adam Smith was a Scottish economist and philosopher who was a pioneer in the thinking of political economy and key figure during the Scottish Enlightenment. Seen by some as "The Father of Economics" or "The Father of Capitalism", he wrote two classic works, The Theory of Moral Sentiments (1759) and An Inquiry into the Nature and Causes of the Wealth of Nations (1776). The latter, often abbreviated as The Wealth of Nations, is considered his magnum opus and the first modern work that treats economics as a comprehensive system and as an academic discipline. Smith refuses to explain the distribution of wealth and power in terms of God's will and instead appeals to natural, political, social, economic, legal, environmental and technological factors and the interactions among them. Among other economic theories, the work introduced Smith's idea of absolute advantage.
