The Quartet on the Middle East or Middle East Quartet, sometimes called the Diplomatic Quartet or Madrid Quartet or simply the Quartet, is a foursome of nations and international and supranational entities involved in mediating the Israeli–Palestinian peace process. The Quartet comprises the United Nations, the United States, the European Union, and Russia. The group was established in Madrid in 2002, recalling the Madrid Conference of 1991, as a result of the escalating conflict in the Middle East.
