Mediomatrici ( Gaulish: *Medio-m?teres) were a Belgic tribe dwelling in the present-day Lorraine region during the Iron Age and the Roman period.
They are mentioned as
Mediomatricorum and Mediomatricis (dat.) by Caesar (mid-1st c. BC),  Mediomatrikoì (? ) by Strabo (early 1st c. AD),  Mediomatrici by Pliny (1st c. AD),  Mediomatricos (acc.) by Tacitus (early 2nd c. AD), and as  Mediomátrikes (?) by Ptolemy (2nd c. AD).  
ethnonym Mediomatrici is a Latinized form of the Gaulish *Medio-m?teres, which literally means 'Middle-Mothers'. It is formed with the root medio- ('in the middle, central') attached to a plural form of m?t?r ('mother'). The name could be interpreted as meaning 'those who live between the Matrona (Marne) and the Matra rivers' (i.e. the mother-rivers), or possibly as the 'Mothers of the Middle-World' (i.e. between the heaven and the underworld).
The city of
Metz, attested ca. 400 AD as civitas Mediomatricorum (' of the Mediomatrici'), is named after the Celtic tribe. civitas
Mediomatrici stater. Ca. 100 BC.
The territory of the Mediomatrici comprised the upper basins of the rivers
Maas, Moselle and Saar, and extended eastwards as far as the Rhine in the mid-first century BC. Ptolemy places them south of the Treviri, between the Remi and the Leuci. 
Their chief town was
('place of the gods, divine enclosure'), Divodurum mentioned by [note 1] Tacitus in the early 1st century AD.
A secondary agglomeration, whose original name is unknown, was located in
Bliesbruck, in the eastern part of their . civitas
Gallic Wars (58-50 BC), the Mediomatrici sent 5,000 men to support Vercingetorix who was besieged in Alesia in 52. In 69-70 of the Common Era, their capital Divodurum was sacked by the armies of Vitellius, and 4,000 of its inhabitants massacred. The Romanization of the Metromatrici was apparently slower compared to their neighbours the Treviri.
Elements of the Mediomatrici may have settled near
Novara, in northwestern Italy, where place-names allude to their presence, such as Mezzomerico, attested as Mediomadrigo in 980.
