The International Criminal Court (ICC or ICCt) is an intergovernmental organization and international tribunal seated in The Hague, Netherlands. It is the first and only permanent international court with jurisdiction to prosecute individuals for the international crimes of genocide, crimes against humanity, war crimes and the crime of aggression. It is distinct from the International Court of Justice, an organ of the United Nations that hears disputes between states.

The ICC began operations on 1 July 2002, upon the entry into force of the Rome Statute, a multilateral treaty that serves as the court's charter and governing document. States which become party to the Rome Statute become members of the ICC, serving on the Assembly of States Parties, which administers the court. As of March 2022, there are 123 ICC member states; 42 states have neither signed nor become parties to the Rome Statute.Intended to serve as the "court of resort", the ICC complements existing national judicial systems and may exercise its jurisdiction only when national courts are unwilling or unable to prosecute criminals. It lacks universal territorial jurisdiction and may only investigate and prosecute crimes committed within member states, crimes committed by nationals of member states, or crimes in situations referred to the Court by the United Nations Security Council.

The ICC has four principal organs: the Presidency, the Judicial Divisions, the Office of the Prosecutor and the Registry. The President is the most senior judge chosen by his or her peers in the Judicial Division, which is composed of eighteen judges and hears cases before the Court. The Office of the Prosecutor is headed by the Prosecutor, who investigates crimes and initiates criminal proceedings before the Judicial Division. The Registry is headed by the Registrar and is charged with managing all the administrative functions of the ICC, including the headquarters, detention unit, and public defense office. The ICC employs over 900 personnel from roughly 100 countries and conducts proceedings in English and French.The ICC held its first hearing in 2006, concerning war crimes charges against Thomas Lubanga Dyilo, a Congolese warlord accused of recruiting child soldiers; his subsequent conviction in 2012 was the first in the court's history. The Office of the Prosecutor has opened twelve official investigations and is conducting an additional nine preliminary examinations. A total of 46 individuals have been indicted in the ICC, including Ugandan rebel leader Joseph Kony, former President Omar al-Bashir of Sudan, President Uhuru Kenyatta of Kenya, Libyan head of state Muammar Gaddafi, President Laurent Gbagbo of Ivory Coast and former Vice President Jean-Pierre Bemba of the Democratic Republic of the Congo.

While praised as a major step towards justice, and as an innovation in international law and human rights, the ICC has faced a number of criticisms from governments and civil society, including objections to its jurisdiction, accusations of bias, Eurocentrism and racism, questioning of the fairness of its case-selection and trial procedures, and doubts about its effectiveness.
