Gallcobar is an Old Irish masculine given name, the archaic form of Gallchobhar. The name derives from the Old Irish elements gall meaning "stranger" or "foreigner" and cobar meaning "desiring" or "cager". Thus, Gallcobar likely carried the sense of "one who desires foreigners" or "eager for strangers," perhaps originally a nickname or epithet.
In early medieval Ireland, Gallcobar was primarily used among Gaelic nobility, particularly in areas with Viking contact where the term gall often referred to Norse settlers. While the name faded after the Old Irish period, it survived in the more familiar modern form Gallchobhar, which in turn gave rise to Irish surnames like Gallagher.
