TheAbroi (Ancient Greek:Ἄβροι) were anIllyrian tribe. They may have been a constituent northern tribe of the larger group of theTaulantii, on theAdriatic coast of southernIllyria (present-dayAlbania).[1][2]
The tribe is mentioned solely byHecataeus of Miletus (6th century BCE), in fragment 69 ofPeriodos ges, cited byStephanus of Byzantium (6th century CE). The name of the tribe is recorded inAncient Greek asἌβροιAbroi.
Their name may have actually beenArboi asAbroi may have been produced via ametathesis, another linguistic process or a common misassociation by Hecataeus of their name with the ancient Greek termabros to better adapt it to Greek. The nameArboi would link them to the IllyrianAlbanoi, who are attested in the same area in the 2nd century CE.[3]
N. G. L. Hammond has pointed out that the nameAbroi andAlbanoi gave rise to the nameAlbania/Albanians, similar to the spread of the nameIllyria/Illyrians from a small group of people on the Adriatic coast, theIllyrioi. This process can also be seen in the case ofGraeci andHellenes.[4]

Hecataeus places them near theTaulantii who lived along the Adriatic and theEnchelei. In modern scholarship the Abroi are generally placed near theMat andDrin valleys. The Abroi may have been a constituent northern tribe of the larger group of the Taulantii.[1][2]
They could preparemead, a wine from honey, and were known to theAncient Greek writers for that method.[1][2]
