The Iemerii (Gaulish: *Iemerioi, 'the twins') were a Celto-Ligurian tribe dwelling in the Val Chisone (Cottian Alps) during the Iron Age.
They are mentioned as Iemeriorum on an inscription.[1]
The ethnic name Iemerii is a Latinized form of *Iemerioi, which can be compared with the Gaulish noun iemurioi, meaning 'twins'.[2]
The Iemerii lived in the Val Chisone, in the Cottian Alps.[3] Their territory was located north of the Maielli, west of the Taurini.[4]
They appear on the Arch of Susa, erected by Cottius in 9–8 BC.[5]
