The Royal Danish Orchestra is a Danish orchestra based in Copenhagen. The Danish name for the orchestra indicates its original function as an ensemble geared to supplying the music for court events.

Carl Nielsen served with the orchestra for many years, partly as 2nd violinist and partly as conductor. King Frederik IX enjoyed a particularly close relationship with the Royal Danish Orchestra, pursuing with its members his interest for the art of conducting. , home of the Royal Danish Orchestra since 1874.
