The Helsinki Accords, Helsinki Final Act, or Helsinki Declaration was the final act of the Conference on Security and Co-operation in Europe held in Finlandia Hall of Helsinki, Finland, during July and August 1, 1975.

Thirty-five states, including the USA, Canada, and most European states except Albania, signed the declaration in an attempt to improve relations between the Communist bloc and the West. The Helsinki Accords, however, were not binding as they did not have treaty status

The Accords' "Declaration on Principles Guiding Relations between Participating States" (also known as "The Decalogue") enumerated the following 10 points:

1. Sovereign equality, respect for the rights inherent in sovereignty
2. Refraining from the threat or use of force
3. Inviolability of frontiers
4. Territorial integrity of States
5. Peaceful settlement of disputes
6. Non-intervention in internal affairs
7. Respect for human rights and fundamental freedoms, including the freedom of thought, conscience, religion or belief
8. Equal rights and self-determination of peoples
9. Co-operation among States
10. Fulfillment in good faith of obligations under international law
