The Royalty Theatre was a small London theatre situated at 73 Dean Street, Soho. Established by the actress Frances Maria Kelly in 1840, it opened as Miss Kelly's Theatre and Dramatic School and finally closed to the public in 1938. The architect was Samuel Beazley. The theatre's opening was ill-fated, and it was little used for a decade. It changed its name twice and was used by an opera company, amateur drama companies and for French pieces.
