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.
The ethnic name Iemerii is a Latinized form of *Iemerioi, which can be compared with the Gaulish noun iemurioi, meaning 'twins'.
The Iemerii lived in the Val Chisone, in the Cottian Alps. Their territory was located north of the Maielli, west of the Taurini.
They appear on the Arch of Susa, erected by Cottius in 9âÂÂ8 BC.
