The International Criminal Court Moot Court Competition or ICCMCC is an annual international moot court competition on international criminal law that is held at The Hague and organised by the Grotius Centre for International Legal Studies of Leiden University, The Hague Campus, with the institutional support of the International Criminal Court and International Bar Association. Established in 2005.
Judges of the competition include ICC judges and officers, and teams have to present arguments based on a fictitious problem via the roles of the prosecution counsel, defence counsel, government counsel, or victim's representative. For the English edition of the moot, each country can only send two to three teams to participate; where necessary, regional rounds and national are organised to select the teams that will compete in the international rounds. In 2020, the oral rounds were cancelled due to COVID-19, and in 2021, the competition adopted an online format due to continuing travel restrictions.
