Marcus Fabius Quintilianus (c. 35 – c. 100 AD) was a Roman educator and rhetorician from Hispania, widely referred to in medieval schools of rhetoric and in Renaissance writing. In English translation, he is usually referred to as Quintilian (), although the alternate spellings of Quintillian and Quinctilian are occasionally seen, the latter in older texts.
