Czech Radio (Czech: Český rozhlas, ČRo) is the public radio broadcaster of the Czech Republic operating continuously since 1923. It is the oldest national radio broadcaster in continental Europe and the second-oldest in Europe after the BBC. Czech Radio was established in 1992 by the Czech Radio Act, which sets out the framework for its operation and finance. It acts as the successor to the previous state-owned Czechoslovak Radio which ceased to exist by 1992.

The service broadcasts throughout the Czech Republic nationally and locally. Its four national services are Radiožurnál, Dvojka, Vltava and Plus. Czech Radio operates twelve nationwide stations and another fourteen regional stations. All ČRo stations broadcast via internet stream, digital via DAB+ and DVB, and part analog via terrestrial transmitters. It is based in Prague in a building in Vinohradská třída.
