The Comedy of Errors is one of William Shakespeare's early plays. It is his shortest and one of his most farcical comedies, with a major part of the humour coming from slapstick and mistaken identity, in addition to puns and word play. The Comedy of Errors (along with The Tempest) is one of only two of Shakespeare's plays to observe the classical unities. It has been adapted for opera, stage, screen and musical theatre.

The Comedy of Errors tells the story of two sets of identical twins that were accidentally separated at birth. Antipholus of Syracuse and his servant, Dromio of Syracuse, arrive in Ephesus, which turns out to be the home of their twin brothers, Antipholus of Ephesus and his servant, Dromio of Ephesus. When the Syracusans encounter the friends and families of their twins, a series of wild mishaps based on mistaken identities lead to wrongful beatings, a near-seduction, the arrest of Antipholus of Ephesus, and false accusations of infidelity, theft, madness, and demonic possession.

William Shakespeare ( 26 April 1564–23 April 1616) was an English poet, playwright, and actor, widely regarded as the greatest writer in the English language and the world's pre-eminent dramatist. He is often called England's national poet and the "Bard of Avon". His extant works, including some collaborations, consist of around 38 plays, 154 sonnets, two long narrative poems, and a few other verses, of which the authorship of some is uncertain. His plays have been translated into every major living language and are performed more often than those of any other playwright.
