Edward Bolesław Osóbka-Morawski ['edvart ɔˈsupka mɔˈrafskʲi] ⓘ (5 October 1909 – 9 January 1997) was a Polish activist and politician in the Polish Socialist Party (PPS) before World War II, and after the Soviet takeover of Poland, Chairman of the Communist-dominated interim government, the Polish Committee of National Liberation (Polski Komitet Wyzwolenia Narodowego) formed in Lublin with Stalin's approval.

Several months later, in June 1945, he was appointed Prime Minister of the Provisional Government of National Unity (Tymczasowy Rząd Jedności Narodowej), in office until February 1947.

However, another prominent socialist, Józef Cyrankiewicz argued that the PPS should support the communists while opposing the creation of a one-party state.

The Communists, with Soviet support, played on this division and forced Osóbka-Morawski to resign in favour of Cyrankiewicz.

Nonetheless, in 1949 he was dismissed from his new post as the Minister of Public Administration, for "deviationist" tendencies.
