Slavko Osterc (17 June 1895 – 23 May 1941), was a Slovenian composer.
Osterc was born in Veržej. He studied under Emerik Beran, who was a pupil of Leoš Janáček, in his youth before attending the Prague Conservatory from 1925 to 1927. While there he studied under Karel Boleslav Jirák, Vítězslav Novák, and Alois Hába. Osterc was a professor at the Ljubljana Conservatory for much of his career, remaining there until his death. He was much the leading composer of Slovenia in the 1930s, as Marij Kogoj had been in the 1920s. One of his pupils was Pavel Šivic.
