The Maastricht Treaty ([maːˈstrɪxt]; formally, the Treaty on European Union or TEU) undertaken to integrate Europe was signed on 7 February 1992 by the members of the European Community in Maastricht, Netherlands. On 9–10 December 1991, the same city hosted the European Council which drafted the treaty. Upon its entry into force on 1 November 1993 during the Delors Commission, it created the three pillars structure of the European Union and led to the creation of the single European currency, the euro.

TEU comprised two novel titles respectively on Common Foreign and Security Policy and Cooperation in the Fields of Justice and Home Affairs, which replaced the former informal intergovernmental cooperation bodies named TREVI and European Political Cooperation on EU Foreign policy coordination. In addition TEU also comprised three titles which amended the three pre-existing community treaties: Treaty establishing the European Atomic Energy Community, Treaty establishing the European Coal and Steel Community, and the Treaty establishing the European Economic Community which had its abbreviation renamed from TEEC to TEC (being known as TFEU since 2007).

The Maastricht Treaty (TEU) and all pre-existing treaties, has subsequently been further amended by the treaties of Amsterdam (1997), Nice (2001) and Lisbon (2009).
