Bawnboy (Irish: an Bádhún Buí, meaning "the yellow bawn") is a small village in a valley at the foot of Slieve Rushen, between Ballyconnell and Swanlinbar, in County Cavan, Ireland. The current population is about 250. A bawn is the defensive wall surrounding an Irish tower house. It is the anglicised version of the Irish word badhún meaning "cattle-stronghold" or "cattle-enclosure" – its original purpose was to protect cattle during an attack. The remains of a late medieval bawn is to be seen at Bawnboy House, which is the origin of the village name. The earliest surviving mention of the placename is in the 1664 Hearth Money Rolls for Templeport where it is called Baonboy. Another name for the village is Kilsub or Kilsob.
