Template:ICC member states

, 124 states are parties to the Statute of the Court, including all the countries of South America, nearly all of Europe, most of Oceania and roughly half of Africa. Burundi and the Philippines were member states, but later withdrew effective 27 October 2017 and 17 March 2019, respectively. A further 31 countries have signed but not ratified the Rome Statute. The law of treaties obliges these states to refrain from "acts which would defeat the object and purpose" of the treaty until they declare they do not intend to become a party to the treaty. Four signatory states—Israel in 2002, the United States on 6 May 2002, Sudan on 26 August 2008, and Russia on 30 November 2016 —have informed the UN Secretary General that they no longer intend to become states parties and, as such, have no legal obligations arising from their signature of the Statute.

Forty-one additional states have neither signed nor acceded to the Rome Statute. Some of them, including China and India, are critical of the Court. Ukraine, a non-ratifying signatory, has accepted the Court's jurisdiction for a period starting in 2013.
