Polskie Radio Spółka Akcyjna (PR S.A.; English: Polish Radio) is Poland's state-owned national public-service radio broadcasting organization.
Polskie Radio was founded on 18 August 1925 and began making regular broadcasts from Warsaw on 18 April 1926.
Czesław Miłosz, recipient of the 1980 Nobel Prize in Literature, worked as a literary programmer at Polish Radio Wilno in 1936.
Before the Second World War, Polish Radio operated one national channel – broadcast from 1931 from one of Europe's most powerful longwave transmitters, situated at Raszyn just outside Warsaw and destroyed in 1939 due to invasion of German Army – and nine regional stations:
- Kraków from 15 February 1927
- Poznań from 24 April 1927
- Katowice from 4 December 1927
- Wilno from 15 January 1928
- Lwów from 15 January 1930
- Łódź from 2 February 1930
- Toruń from 15 January 1935
- Warszawa from 1 March 1937 – known as Warszawa II, the national channel becoming Warszawa I from this date
- Baranowicze from 1 July 1938
A tenth regional station was planned for Łuck, but the outbreak of war meant that it never opened.
After the war, Polskie Radio came under the tutelage of the state public broadcasting body Komitet do Spraw Radiofonii "Polskie Radio" (later "Polskie Radio i Telewizja" – PRT, Polish Radio and Television). This body was dissolved in 1992, Polskie Radio S.A. and Telewizja Polska S.A. becoming politically dependent corporations, each of which was admitted to full active membership of the European Broadcasting Union on 1 January 1993.
