The North Atlantic Treaty Organization, also called the North Atlantic Alliance, is an intergovernmental military alliance of 31 member states – 29 European and two North American. Established in the aftermath of World War II, the organization implemented the North Atlantic Treaty, signed in Washington, D.C., on 4 April 1949. NATO is a collective security system: its independent member states agree to defend each other against attacks by third parties. During the Cold War, NATO operated as a check on the threat posed by the Soviet Union. The alliance remained in place after the dissolution of the Soviet Union and the Warsaw Pact and has been involved in military operations in the Balkans, the Middle East, South Asia, and Africa. The organization's motto is animus in consulendo liber.

The North Atlantic Treaty Organisation (NATO)'s Military Committee (MC) is the body that is composed of member states' Chiefs of Defence (CHOD). These national CHODs are regularly represented in the MC by their permanent Military Representatives (MilRep), who often are two- or three-star flag officers.

The secretary general does not have a military command role; political, military and strategic decisions ultimately rest with the member states. Together with the Chair of the NATO Military Committee and the supreme allied commander, the officeholder is one of the foremost officials of NATO.
The Structure of the North Atlantic Treaty Organization is complex and multi-faceted.

The history of the North Atlantic Treaty Organization (NATO) begins in the immediate aftermath of World War II when British diplomacy set the stage to contain the Soviet Union and to stop the expansion of Soviet power in Europe. The United Kingdom and France signed, in 1947, the Treaty of Dunkirk, a defensive pact, which was expanded in 1948 with the Treaty of Brussels to add the three Benelux countries and committed them to collective defense against an armed attack for fifty years. The British worked with Washington to expand the alliance into NATO in 1949, adding the United States and Canada as well as Italy, Portugal, Norway, Denmark, and Iceland. Greece and Turkey joined in 1952, West Germany joined in 1955, Spain joined in 1982, Czech Republic, Hungary and Poland joined in 1999, Bulgaria, Estonia, Latvia, Lithuania, Romania, Slovakia, and Slovenia joined in 2004, Albania and Croatia joined in 2009, Montenegro joined in 2017, North Macedonia joined in 2020, and Finland joined in 2023.

The European Union (EU) and the North Atlantic Treaty Organisation (NATO) are two main treaty-based Western organisations for cooperation between member states, both headquartered in Brussels, Belgium. Their natures are different and they operate in different spheres: NATO is a purely intergovernmental organisation functioning as a military alliance, which serves to implement article 5 of the North Atlantic Treaty on collective territorial defence. The EU on the other hand is a partly supranational and partly intergovernmental sui generis entity akin to a confederation that entails wider economic and political integration. Unlike NATO, the EU pursues a foreign policy in its own right—based on consensus, and member states have equipped it with tools in the field of defence and crisis management; the Common Security and Defence Policy (CSDP) structure.
