La Soeur de la reine is a burlesque French-language play written by Algernon Charles Swinburne in the 1860s. The comedy of the piece derives from its parody of the full-bloodedly Romantic style of Victor Hugo's prose plays, and from its portrayal of a profligate and tyrannical Queen Victoria whose numerous affairs with her prime ministers and with William Wordsworth are the scandal of the age. Though Swinburne sometimes read from the play to his friends, for whose amusement it was primarily intended, he did not publish it, and the surviving manuscripts, comprising Acts 2 and 4 (the latter perhaps incomplete), were not published until 1964. It is now considered a triumph of satirical humour.
