Devi Dja (1914–1989), known as Miss Dja, was an Indonesian dancer, playwright and film actor in the 1940s. A member of the Dardanella Opera group, founded by her husband, Willy A. Piedro, which toured the Dutch East Indies, she moved with her husband to the US around 1940, remaining there for the rest of her life as a professional entertainer and taking on American citizenship.

Dardanella was a touring theatre company from the Dutch East Indies established by Willy A. Piedro in 1926. Arising from a background of musical theatre, the troupe focused on realistic stories, both adaptations of foreign works and original stage plays about life in the Indies. Starring Dewi Dja' and Tan Tjeng Bok, the troupe performed original works by Piedro and Andjar Asmara. Popular both in the Indies and abroad, Dardanella dissolved during an international tour after 1936. Several of its members later went into film.
