The Coriondi (Κοριονδοί) were a people of early Ireland, referred to in Ptolemy's 2nd century Geography as living in southern Leinster.
[1] The stem *corio- ('army' or 'troop of warriors'), which is derived from Proto-Indo-European *kóryos ('army, people under arms'), also occurs in Gaulish and Brittonic personal and tribal names such as Coriosolites, Petrucorii, and Corionototae.
[2] The Benntraige, a people dwelling in southern Ireland in pre-Christian times, might be a remnant of the tribe.
[3] Eoin MacNeill identified another later Irish group, the Coraind, in the Boyne valley, as possibly the same people.
[4] Other possibly related names include the Corcu Cuirnd,[4] Cuirennrige and Dál Cuirind in early medieval Ireland, and in Britain, the Corionototae, known from an inscription in Hexham, Northumberland, and Corinion, the Brittonic name for Cirencester, Gloucestershire.
