List of hillforts in Northern Ireland
# List of hillforts in Northern Ireland

Northern Ireland, like the rest of the British Isles, is dotted with hillforts. The Atlas of Hillforts of Britain and Ireland lists thirty-two such forts. These are classically defined as small hilltop settlements fortified with earthworks, but many are not located on hills, and probably did not function as forts. Their function is unclear; although conventionally interpreted as defensive fortifications and centres of economic political power, there is little evidence that they were ever attacked, and more recent scholarship has suggested that they may be better interpreted as monuments.
