Cornelius Fuscus (died 86) is a Roman general who fights campaigns under the Emperors of the Flavian dynasty.
During the reign of Domitian, he serves as prefect of the imperial bodyguard, known as the Praetorian Guard, from 81 until his death in 86.
Before this appointment, Fuscus had distinguished himself as one of Vespasian's most ardent supporters during the civil war of 69, known as the Year of the Four Emperors.
In 85 the Dacians, led by King Decebalus, invade the Roman Empire at Moesia, a province located south of the Danube.
In response, Domitian dispatches Cornelius Fuscus to the region with five legions.
Although Fuscus is initially successful in driving the invaders back across the border, the prefect suffers defeat when he is ambushed along with Legio V Alaudae during an expedition into Dacia, at the First Battle of Tapae.
The entire legion is annihilated, and Fuscus killed.
