Olga Gzovskaya (Russian: О́льга Влади́мировна Гзо́вская; 10 October 1883 – 2 July 1962) was a Russian Empire and Soviet theater and film actress.

The Moscow Art Theatre production of Hamlet was a 1911–12 production of Hamlet, produced by Konstantin Stanislavski and Edward Gordon Craig. It is particularly important in the history of performances of Hamlet and of 20th-century theatre in general. Despite hostile reviews from the Russian press, the production attracted enthusiastic and unprecedented worldwide attention for the theatre, with reviews in Britain's The Times and in the French press that praised its unqualified success. The production placed the Moscow Art Theatre "on the cultural map for Western Europe", and it came to be regarded as a seminal event that influenced the subsequent history of production style in the theatre and revolutionised the staging of Shakespeare's plays in the 20th century. It became "one of the most famous and passionately discussed productions in the history of the modern stage."
