The Dortmunder Philharmoniker are a German symphony orchestra based in Dortmund, North Rhine-Westphalia, with origins in the city's municipal orchestral tradition dating to the late 19th century and serving as the resident ensemble of Dortmund's concert hall. Primarily performing classical symphonic repertoire, opera and contemporary works, they maintain a programme that balances standard orchestral literature with commissions and collaborations that reflect Dortmund's cultural scene and civic music-making.
