A Woman of No Importance is a play by Irish playwright Oscar Wilde. The play premièred on 19 April 1893 at London's Haymarket Theatre. Like Wilde's other society plays, it satirizes English upper class society. It has been performed on stages in Europe and North America since his death in 1900.
Herbert Beerbohm Tree, actor-manager of London's Haymarket Theatre, asked Oscar Wilde to write him a play following the success of Wilde's Lady Windermere's Fan at the St. James Theatre. Wilde was initially quite reluctant since the character Tree would take was not the sort of part he associated with the actor: Wilde went so far as to describe Lord Illingworth as himself.
