Artistic license (also known as dramatic license, historical license, poetic license, narrative license, licentia poetica, or simply license) is a colloquial term, sometimes euphemism, used to denote the distortion of fact, alteration of the conventions of grammar or language, or rewording of pre-existing text made by an artist to improve a piece of art.

The artistic license may also refer to the ability of an artist to apply smaller distortions, such as a poet ignoring some of the minor requirements of grammar for poetic effect. For example, Mark Antony's "Friends, Romans, Countrymen, lend me your ears" from Shakespeare's Julius Caesar would technically require the word "and" before "countrymen", but the conjunction "and" is omitted to preserve the rhythm of iambic pentameter (the resulting conjunction is called an asyndetic tricolon). Conversely, on the next line, the end of "I come to bury Caesar, not to praise him" has an extra syllable because omitting the word "him" would make the sentence unclear, but adding a syllable at the end would not disrupt the meter. Both of these are examples of artistic license.
