Pauline Rita, born Margaret Glenister, was an English soprano and actress. During her early career, she was best known for her performances in operettas and comic operas at the Opera Comique and was associated with impresario Richard D'Oyly Carte. Later she married flautist John Radcliff, and the two performed together for many years.

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.
