Vera Vasilyevna Zorina (Russian: Вера Васильевна Зорина ; real surname - Popova; 1853 - 1903) was a Russian operetta singer (mezzo-soprano), best known as a Russian romances (or 'Gypsy art-songs') performer.
 She became famous after playing the part of Stesha in the popular musical "Gypsy Songs in Characters" by Nikolai Kulikov.
 Another highly popular part of hers was La Périchole in the Jacques Offenbach's operetta.
 Vera Zorina (an ethnic Russian) is regarded as a founder of the "Gypsyan line" in Russian operetta.
La Périchole (] ) is an opéra bouffe in three acts by Jacques Offenbach.
 Henri Meilhac and Ludovic Halévy wrote the French-language libretto based on the 1829 one act play "Le carrosse du Saint-Sacrement" by Prosper Mérimée, which was revived on 13 March 1850 at the Théâtre-Français.
 Offenbach was probably aware of this production, as he conducted the orchestra of the Comédie-Française from around this time.
 Another theatrical creation that pre-dates Offenbach's opéra bouffe and may have influenced the piece is a farce by Desforges and Théaulon given on 21 October 1835 at the Théâtre du Palais-Royal.
