Wilsonianism or Wilsonian are words used to describe a certain type of ideological perspectives on foreign policy. The term comes from the ideology of United States President Woodrow Wilson and his famous Fourteen Points that he believed would help create world peace if implemented.
Common principles that are often associated with "Wilsonianism" include:
- Advocacy of the spread of democracy
- Advocacy of the spread of capitalism 
- Opposition to isolationism and non-interventionism
- Pro-imperialism, in favor of intervention to further national self-interest.
- Presidents Bill Clinton, George W. Bush, and Barack Obama have been repeatedly referenced as continuing the progressive tradition of Wilsonianism in America. This is primarily due to their continuing efforts of nation building and interventionism.
- Bill Clinton's nation building in The Balkans around the time of the Bosnian War.
- George Bush's nation building and interventionism in Iraq and Afghanistan during the war on terrorism.
- Barack Obama's continuation of the former Bush white house's foreign policy and his own intervention in the 2011 Libyan civil war.
- Former U.S. Secretary of State Henry Kissinger once described the making of American foreign policy as an ongoing conflict between Wilsonians and Jacksonites.
Critics of the concept of "Wilsonian idealism" say that Wilson only wanted ethnic self-determination and democracy in European countries which were under the control of rivals of America. Elsewhere such principles were ignored. Modern critics such as paleoconservatives argue the principles are overly idealistic and can lead to unnecessary military interventions, putting lives at risk over abstract concepts rather than direct threats.
The legacy of President Wilson in domestic interventionism is sometimes also referred to as Wilsonianism.
In the United Kingdom, the term "Wilsonian" or, rarely, "Wilsonism," is sometimes used to refer to the ideas associated with former Labour Prime Minister Harold Wilson, usually relating to his time in office from 1964-70 rather than his troubled return from 1974-76. It usually suggests the idea of "classless" technocratic social democracy, which inspired much of excitement in Great Britain around the time of his landslide victory in the 1966 general election and is often related to his famous comment about "the white heat of technological revolution."
