Jastrzębie-Zdrój Agreement (Polish: Porozumienie jastrzebskie) was an accord, signed on September 3, 1980 at Manifest Lipcowy Coal Mine in Jastrzębie-Zdrój, between the authorities of the People's Republic of Poland, and the Jastrzebie-Zdroj Interfactory Strike Committee. The agreement was signed by a government envoy Aleksander Kopec, and leader of the Committee, Jaroslaw Sienkiewicz. It was the last of the three accords, signed in late summer of 1980 in Poland. These accords resulted in creation of Solidarity, and as such, Jastrzębie-Zdrój Agreement is regarded as part of the August Agreements.
