Cairrge Brachaidhe, aka Carrickbraghy or Carrichbrack, a Gaelic-Irish medieval territory located in Inishowen, County Donegal, Ireland.
Thought to have been named after, or by, Brachaidi mac Diarmata of the Cenél Fergusa (see List of Irish clans in Ulster), a clan who held the territory from the early medieval period. The family of Ó Maol Fábhail were its kings.
In the early modern era it was part of the barony of Inishowen West, in County Donegal.
