Jerzy Władysław Giedroyc (27 July 1906 – 14 September 2000) was a Polish writer and political activist.
During World War II he served under General Władysław Anders in the Polish Army and kept up friendly contacts with representatives of other nationalities. After the war he moved to Paris, where he published and edited a leading Polish-émigré literary-political journal, Kultura (1947–2000), which promoted a peaceful settlement of Poland's eastern borders, and accepting the results of the Molotov-Ribbentrop Pact and the Yalta Conference (Gedroyc-Mieroszewski doctrine), even though many Poles regarded these as betrayals of Poland; this helped lay the groundwork for Poland's successful eastern policy after the fall of communism.
His closest collaborator was Juliusz Mieroszewski, who provided the theoretical justification for Polish recognition of the borders with Ukraine, Belarus, and Lithuania (whose future independence he predicted long before it came about).
In 2006 the Polish Sejm declared the year 2006 to be the "Year of Jerzy Giedroyc."
