Pescennius Niger (Latin: Gaius Pescennius Niger Augustus; c. 135 - 140–194) is a Roman usurper from 193 to 194 during the Year of the Five Emperors.

He claims the imperial throne in response to the murder of Pertinax and the elevation of Didius Julianus, but is defeated by a rival claimant, Septimius Severus and killed while attempting to flee from Antioch.
