Drottningholm Court Theatre Orchestra is the resident orchestra of the Drottningholm Palace Theatre in Sweden, with origins linked to the theatre's 18th-century foundation and a modern identity as a historical-performance ensemble specialising in baroque and classical opera and theatrical repertoire. Performing primarily on period instruments and employing historically informed practices, the orchestra focuses on 18th-century opera and theatre music and plays a role in the revival and continued presentation of historical theatre repertoire within Sweden's cultural landscape.
