Maria is a fictional character in the play Twelfth Night by William Shakespeare. She is a servant in Olivia's household. Maria is shown to have a friendly relationship with Sir Toby Belch, and exhibits a witty attitude. Maria also forges a love letter to Malvolio which results in Malvolio being confined to a dark room (a treatment for madness). In the end of the play, this relationship with Sir Toby Belch ultimately leads to their marriage.
