The Prague Radio Symphony Orchestra (Symfonický orchestr Českého rozhlasu) is based in Prague in the Czech Republic.

Regular radio broadcasting began in the Czech Republic in May, 1923. Live classical musical broadcasts became very popular. It was soon realized that a full-time dedicated orchestra was required and on October 1, 1926, the Radiojournal Orchestra was founded under conductor Jozka Charvát.

In 1952, the popularity and size of the Radiojournal Orchestra was such that a second orchestra, the Prague Radio Symphony Orchestra, was split off from the Radiojournal Orchestra.
