The Radio Filharmonisch Orkest (Radio Philharmonic Orchestra; Dutch abbreviation RFO) is a Dutch radio orchestra, based in Hilversum. The RFO performs under the aegis of the Muziekcentrum van de Omroep (Broadcasting Music Centre; NMBC), an umbrella organization bringing together the music departments of the various broadcasting associations affiliated to Nederlandse Publieke Omroep (Dutch Public Broadcasting).

The RFO performs on NPO Radio 4 and gives public concerts in Amsterdam and Utrecht. It has also served as the orchestra for productions at De Nederlandse Opera. The RFO's programmes are decided by the above-mentioned Muziekcentrum, rather than directly by the orchestra's management and chief conductor. The current manager of the RFO is Wouter den Hond.
