Dutch National Opera (DNO; formerly De Nederlandse Opera, now De Nationale Opera in Dutch) is a Dutch opera company based in Amsterdam, Netherlands. Its present home base is the Dutch National Opera & Ballet housed in the Stopera building, a modern building designed by Cees Dam and Wilhelm Holzbauer which opened in 1986.
DNO was established shortly after the end of World War II as a repertory company with a permanent ensemble. In the postwar period, it toured extensively in the Netherlands from its home base in the Stadsschouwburg, a fin de siècle theatre on the Leidseplein in Amsterdam. In 1964, it was renamed De Nederlandse Operastichting. (The Dutch Opera Foundation), and the company adopted a stagione orientation, inviting different soloists and artistic teams for each new production. In 1986, the company moved to the new Stopera building, which it shares with the Dutch National Ballet, and thereafter became known as De Nederlandse Opera (DNO). In 2014, the company changed its name to De Nationale Opera (Dutch National Opera).
DNO has its own choir of sixty singers and a technical staff of 260. DNO historically has not had its own resident orchestra, and so various orchestras of the Netherlands, including the Netherlands Philharmonic Orchestra (NPO), the Netherlands Chamber Orchestra (NKO), the Royal Concertgebouw Orchestra, the Rotterdam Philharmonic Orchestra, the Radio Filharmonisch Orkest and the Asko/Schönberg ensemble have provided the orchestral forces for DNO productions.
