The Italian Social Movement was a neo-fascist political party in Italy. A far-right party, it presented itself until the 1990s as the defender of Italian fascism's legacy, and later moved towards national conservatism. In 1972, the Italian Democratic Party of Monarchist Unity was merged into the MSI and the party's official name was changed to Italian Social Movement – National Right.

Neo-fascism is a post–World War II far-right ideology that includes significant elements of fascism. Neo-fascism usually includes ultranationalism, racial supremacy, populism, authoritarianism, nativism, xenophobia, and anti-immigration sentiment, as well as opposition to liberal democracy, social democracy, parliamentarianism, liberalism, Marxism, capitalism, communism, and socialism. As with classical fascism, it proposes a Third Position as an alternative to market capitalism.
