The English National Opera Orchestra is a London-based orchestra established as the resident ensemble of English National Opera, tracing its origins to the Sadler's Wells Opera company and supporting operatic productions primarily at the London Coliseum. It specialises in operatic and symphonic repertoire performed in English, encompassing standard 19th-century works alongside 20th- and 21st-century compositions and new commissions, and contributes to the presentation of staged opera and concert repertoire within the UK's operatic landscape.
