The RTV Slovenia Symphony Orchestra (Slovene: Simfonični orkester RTV Slovenija) was established in 1956 within Radiotelevizija Slovenija. In the 50-year period of its work, it contributed a major part of archive recordings, composed by Slovenian composers, as well as contemporary and classical music from all over the world. Current chief-conductor of the orchestra is En Shao.

The beginnings of The Symphony Orchestra RTV Slovenia reach as far back as 1955 when it was conducted by the professor from the academy of music, the violin virtuoso and composer Uroš Prevoršek. The Orchestra was later conducted by Samo Hubad, Stanislav Macura, Anton Nanut and Lior Shambadal.
