A comedy of errors is a narrative work (often a play) that is light and often humorous or satirical in tone, in which the action usually features a series of comic instances of mistaken identity, and which typically culminates in a happy resolution of the thematic conflict.

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.
