赫尔辛基最终法案（英语：Helsinki Final Act），又称赫尔辛基协议（英语：Helsinki Accords）、赫尔辛基宣言（英语：Helsinki Declaration），欧洲安全与合作会议赫尔辛基最后文档（英文:Helsinki Final Act of the Conference on Security and Co-operation in Europe）

1975年8月，芬兰首都赫尔辛基举行了关于国际安全与欧洲合作的会议，共37个国家（包括美国、加拿大，与除阿尔巴尼亚、安道尔外的全部欧洲国家）签署了这项协议。

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 all 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.
