The Special Tribunal for the Crime of Aggression against Ukraine (STCAU, French: Tribunal spécial pour le crime d'agression contre l'Ukraine) is an ad hoc international criminal tribunal aimed at prosecuting individuals responsible for the Russian invasions of Ukraine under the legal concept of crimes of aggression, as a complement to the existing International Criminal Court investigation in Ukraine.

An agreement between the Council of Europe and Ukraine was signed on 25 June 2025 in Strasbourg. It sets out the conditions for establishing the Tribunal and includes its statute in an annex.

The Tribunal has not yet been established; it will be set up once States have provided legally binding guarantees of political and financial support.
