The Budapest Philharmonic Orchestra (Hungarian: Budapesti Filharmóniai Társaság Zenekara) is Hungary's oldest functioning orchestra, being founded in 1853 by Ferenc Erkel under the auspices of the Budapest Philharmonic Society. For many years it was Hungary's only professional orchestra.

The orchestra is drawn from musicians of the Hungarian State Opera House and the Hungarian National Theatre, and most of its concerts take place at the opera house. It has made numerous concert tours to other European countries, the United States and Japan.
