The Giedroyc doctrine (pronounced [ˈɡʲɛdrɔjt͡s]; Polish: doktryna Giedroycia) was a political doctrine that urged reconciliation among East-Central and East European countries. It was developed by postwar Polish émigrés, and was named for Jerzy Giedroyc, a Polish émigré publicist. Giedroyc developed the doctrine in the 1970s in the journal Kultura with Juliusz Mieroszewski (the doctrine is sometimes called the Giedroyc-Mieroszewski doctrine) and other émigrés of the "Maisons-Laffitte group". The doctrine can be traced to the interwar Prometheist project of Józef Piłsudski.
