A NATO summit is a summit meeting that is regarded as a periodic opportunity for Heads of State and Heads of Government of NATO member countries to evaluate and provide strategic direction for Alliance activities.

NATO summits are not regular meetings like the more frequent NATO ministerial meetings, but rather are important junctures in the alliance’s decision-making process on the highest level. Summits are often used to introduce new policy, invite new members into the alliance, launch major new initiatives, and build partnerships with non-NATO countries.

From the founding of NATO in 1949, there have been a total of twenty-five NATO summits; the last of which was the 2012 Chicago summit held in May 2012. Only the traditional summits have received an official number, thereby excluding the exceptional summit of 2001 in NATO headquarters

The North Atlantic Treaty Organization or NATO ( /ˈneɪtoʊ/ NAY-toh; French: Organisation du traité de l'Atlantique Nord (OTAN)), also called the (North) Atlantic Alliance, is an intergovernmental military alliance based on the North Atlantic Treaty which was signed on 4 April 1949. The organization constitutes a system of collective defence whereby its member states agree to mutual defense in response to an attack by any external party. NATO's headquarters are in Brussels, Belgium, one of the 28 member states across North America and Europe, the newest of which, Albania and Croatia, joined in April 2009. An additional 22 countries participate in NATO's Partnership for Peace, with 15 other countries involved in institutionalized dialogue programs. The combined military spending of all NATO members constitutes over 70% of the world's defence spending.

For its first few years, NATO was not much more than a political association. However, the Korean War galvanized the member states, and an integrated military structure was built up under the direction of two U.S. supreme commanders. The course of the Cold War led to a rivalry with nations of the Warsaw Pact, which formed in 1955. The first NATO Secretary General, Lord Ismay, stated in 1949 that the organization's goal was "to keep the Russians out, the Americans in, and the Germans down." Doubts over the strength of the relationship between the European states and the United States ebbed and flowed, along with doubts over the credibility of the NATO defence against a prospective Soviet invasion—doubts that led to the development of the independent French nuclear deterrent and the withdrawal of the French from NATO's military structure in 1966.

Silvio Berlusconi (Italian pronunciation: [ˈsilvjo berluˈskoːni] ( listen); born 29 September 1936) is an Italian politician and media tycoon who served three times as Prime Minister of Italy from 1994 to 1995, 2001 to 2006 and 2008 to 2011. Berlusconi is also the controlling shareholder of Mediaset and owner of A.C. Milan. He is nicknamed Il Cavaliere (The Knight) for his knighthood to the Order of Merit for Labour, which he received in 1977.

Berlusconi is the longest-serving post-war Prime Minister of Italy, and third longest-serving since Italy's unification, after Benito Mussolini and Giovanni Giolitti, holding three separate terms. Technically, he has been sworn in four times because after a cabinet reshuffle, as happened with Berlusconi in 2005, the new ministry is sworn in and subjected to a vote of confidence. He is the leader of the People of Freedom political movement, a centre-right party he founded in 2009. From November 2009 to November 2011, he was the most senior leader of the G8 countries. In 2012, Forbes magazine ranked him as the 169th richest man in the world with a net worth of US$5.9 billion.
