The Organisation for the Prohibition of Chemical Weapons (OPCW) is the implementing body of the Chemical Weapons Convention (CWC or Convention). The OPCW is given the mandate to achieve the object and purpose of the Convention, to ensure the implementation of its provisions, including those for international verification of compliance with it, and to provide a forum for consultation and cooperation among States Parties.

The Technical Secretariat of the OPCW is responsible for the day-to-day administration and implementation of the Convention, including inspections, while the Executive Council and the Conference of the States Parties are decision-making organs designed primarily to determine questions of policy and resolve matters arising between the States Parties on technical issues or on interpretations of the Convention. The chairs of the Executive Council and the Conference are appointed by each body's membership. The Technical Secretariat is headed by a Director-General, who is appointed by the Conference on the recommendation of the Council.
