Allectus (died 296) was a Roman-Britannic usurper-emperor in Britain and northern Gaul from 293 to 296.

Allectus was treasurer to Carausius, a Menapian officer in the Roman navy who had seized power in Britain and northern Gaul in 286. In 293 Carausius was isolated when the western Caesar, Constantius Chlorus, retook some of his Gallic territories, particularly the crucial port of Bononia (modern Boulogne), and defeated his Frankish allies in Batavia. Allectus assassinated Carausius and assumed command himself.

His reign has left little record, although his coin issues display a similar distribution to those of Carausius. They are found in north western Gaul, indicating that the recapture of Bononia did not spell the end of the rebel empire on that side of the English Channel.

Constantius launched an invasion to depose him in September 296. His forces sailed in several divisions. Constantius led one division from Bononia, but seems to have been delayed by bad weather. Another division, under the praetorian prefect Asclepiodotus, took advantage of fog to avoid Allectus's ships stationed at the Isle of Wight, and landed near Southampton Water, where they burnt their ships. Allectus's forces were forced to retreat from the coast, but were cut off by another of Constantius's divisions and defeated. Allectus himself was killed in the battle, having removed all insignia in the hope that his body would not be identified. Archaeology suggests that Calleva Atrebatum (Silchester) was the site of his defeat. A group of Roman troops, who had been separated from the main body by the fog during the channel crossing, caught up with the remnants of Allectus's men, mostly Franks, at Londinium (London), and massacred them. Constantius himself, it seems, did not reach Britain until it was all over, and his panegyrist claims he was welcomed by the Britons as a liberator.
