The Chamber Choir of Radio Television Ljubljana, also known as the RTV Slovenia Chamber Choir, is a distinguished choral ensemble based in Ljubljana, Slovenia. Established in 1945 by Radio-Television Slovenia (RTV Slovenia), it is one of the oldest radio choirs in Europe. The choir has a rich history of collaboration with the RTV Slovenia Symphony Orchestra and has been led by a series of notable conductors including Franc Kimovec, Drago M. Šijanec, and Mirko Cuderman, among others.

The choir's repertoire spans modern compositions as well as renowned works from musical history, reflecting its dedication to both contemporary and classical music. Throughout its history, the choir has worked with prominent conductors such as Stefan Parkman and Günther Theuring, and it has been involved in significant projects like the radio project Gallus.

In 2004, the choir transitioned to a project-based ensemble, continuing to record works for the Music Production Unit of RTV Slovenia. The choir has been involved in various recordings, including notable performances of Antonin Dvorak's "Stabat Mater."

The RTV Slovenia Chamber Choir remains an integral part of Slovenia's cultural heritage, contributing to the preservation and promotion of choral music both domestically and internationally.
