The Ateneum Theatre in Warsaw () is a Polish dramatic theatre founded in 1928. It resides in a building erected a year earlier in the interwar Poland as headquarters for the Professional Union of PKP Railway Workers with offices upstairs. After World War II, the severely damaged structure was restored to its former glory with public funds. The state-run theatre reopened in 1951; named after its first and already famous prewar director Stefan Jaracz.
The Ateneum Theatre began as an experimental stage with strong socio-political profile, under an Avant-garde-inspired name The Outpost of Spoken Word (Placówka à »ywego Sà Âowa). Its artistic manifesto was influenced by the mainly proletarian Warsaw neighbourhood of Powià Âle in which it was established.
Two years into its existence, the artistic direction of Ateneum was taken over by popular actor Stefan Jaracz (1930). He worked there until the Nazi-Soviet invasion of Poland, sharing his responsibilities with Leon Schiller in 1932âÂÂ33 season, and with Karol Adwentowicz (1934). Together, they raised the theatre's reputation as one of the leading voices for Poland's new intelligentsia. The groundbreaking performances included The Street Scene by Elmer Rice (1930), Danton's Death by Georg Büchner (1931), Senat Szaleà Âców by Holocaust victim Janusz Korczak (1931), the Tsar Lénine by François Porché (1932), and in the vein of political Zeittheater of the time, The Captain of Köpenick by Carl Zuckmayer (1932) and Roar China! by Sergei Tretyakov (1933); not to mention the popular Ladies and Husars (Damy i Huzary) by Aleksander Fredro (1932) and The Open House by Michaà  Baà Âucki.
The neighbourhood of Powià Âle was almost completely destroyed by Nazi German bombardment during the Warsaw Uprising of 1944. The theatre was consumed by fire. It was practically rebuilt after the liberation, based on design by Wiktor Ballogh, with due consideration for its original look. The grand reopening took place on 22 July 1951, with the première of Intervention by Lev Slavin in the spirit of socialist-realist doctrine imposed by the Communist Party in Stalinist Poland. For the next forty years the theatre was under the direction of Janusz Warmià Âski (1922âÂÂ1996) who managed to outlive and outgrow the Soviet system beyond the revolutions of 1989. Almost all prominent Polish actors performed at Ateneum throughout its existence including Jadwiga Andrzejewska, prof. Aleksander Bardini, Henryk Bista, Zbigniew Cybulski, Edward Dziewoà Âski, Jerzy Duszyà Âski, Tadeusz Fijewski, Adam Hanuszkiewicz, Gustaw Holoubek, Emil Karewicz, Bogumià  Kobiela, Jan Kociniak, Agnieszka Osiecka, Aleksandra à Âlàska, and Roman Wilhelmi among others.
