The Commission on Security and Cooperation in Europe, also known as the Helsinki Commission, is an independent U.S. Government agency created in 1976 to monitor and encourage compliance with the Helsinki Final Act and other OSCE commitments.

The Commission consists of nine members from the United States Senate, nine members from the U.S. House of Representatives, and one member each from the Departments of State, Defense, and Commerce. The positions of Chair and Co-Chair are shared by the House and Senate and rotate every two years, when a new Congress convenes. A professional staff assists the Commissioners in their work.

The Commission contributes to the formulation of U.S. policy on the OSCE and takes part in its execution, including through Member and staff participation on U.S. Delegations to OSCE meetings and in certain OSCE bodies. Members of the Commission have regular contact with parliamentarians, government officials, NGOs, and private individuals from other OSCE participating States.

The Commission convenes public hearings and briefings with expert witnesses on OSCE-related issues; issues public reports concerning implementation of OSCE commitments in participating States; and organizes official delegations to participating States and OSCE meetings to address and assess democratic, economic, security and human rights developments firsthand.
