Sadler's Wells Opera Chorus was the resident chorus of the Sadler's Wells Opera in London, formed in the 20th century to perform operatic repertoire—often in English—within the company's staged productions. It specialised in staged operatic and choral works, broadening its repertoire over decades to encompass 19th- and 20th-century opera and later becoming integrated into the chorus framework as the company transitioned into English National Opera.
