The Importance of Being Earnest, A Trivial Comedy for Serious People is a play by Oscar Wilde. First performed on 14 February 1895 at the St James's Theatre in London, it is a farcical comedy in which the protagonists maintain fictitious personæ to escape burdensome social obligations. Working within the social conventions of late Victorian London, the play's major themes are the triviality with which it treats institutions as serious as marriage, and the resulting satire of Victorian ways. Contemporary reviews all praised the play's humour, though some were cautious about its explicit lack of social messages, while others foresaw the modern consensus that it was the culmination of Wilde's artistic career so far. Its high farce and witty dialogue have helped make The Importance of Being Earnest Wilde's most enduringly popular play.

Oscar Wilde (16 October 1854 -30 November 1900) was an Irish playwright, novelist, essayist, and poet. After writing in different forms throughout the 1880s, he became one of London's most popular playwrights in the early 1890s. Throughout his entire life, Wilde remained deeply committed to the principles of aestheticism, principles that he expounded through his lectures and demonstrated through his works as well as anyone of his era.
