Mat (Albanian definite form: Mati, Latin: Mathis) is a municipality in Dibër County, northern Albania.

It was created in 2015 by the merge of the former municipalities Baz, Burrel, Derjan, Komsi, Lis, Macukull, Rukaj and Ulëz.

Today's meaning in Albanian, "river bank, river shore", is a consequence of a secondary change through the common use of both the terms mal, "mountain" and breg, "shore", giving the meaning of "elevation".

[5] Historical linguistic considerations suggest that Mat and the surrounding regions, including Mirdita, have been among the oldest settlements of the Albanians after their ethnogenesis, which is considered to have been completed between the 2nd and the 5th–6th centuries AD.

The territory is largely composed of mountains and hills, which has only been opened up by National Road 6, which links the town of Milot with Peshkopi.
