Olivia is a fictional character from William Shakespeare's play Twelfth Night, believed to have been written around 1600 or 1601.

The play begins with the Duke of Illyria, Orsino, pining away over his love for Olivia while she refuses to accept him as a suitor.

Despite all of the rumpus going on at her home, Olivia refuses all visitors until Orsino sends his new page, the protagonist of the play, Viola, to call on her.

In 2009, Shakespeare in the Park put on a production starring Anne Hathaway as Viola and Audra McDonald as Olivia.

In 2006 the play was adapted into a modern retelling titled She's the Man, starring Amanda Bynes as Viola and Laura Ramsey as Olivia.
