Madame Peacock is a 1920 American silent drama film written, produced by, and starring Alla Nazimova in a dual role.

Distributed by Metro Pictures, copies of the film exist in several collections[1][2] including the Cinematheque Royale de Belgique, Brussels.

[3] As described in a film magazine,[4] the idol of New York City's theater going public Jane Goring (Nazimova), after returning to her apartment after the run of Madame Peacock, finds not the newspaper man she thought was going to interview her but instead her husband Robert McNaughton (Probert) who is wracked with a cough.

Cold, cruel, uncompromising, thoughtless, she keeps the theater company waiting for hours, and then proceeds to break the heart of the playwright, humiliate her fellow players, and exasperate her manager beyond all endurance.

Eventually the play opens, and after the final curtain the audience shouts for Gloria Cromwell, Jane is obliged to relinquish the stage to her.
