Kilnaleck or Kilnalec (Irish: Cill na Leice, meaning "church of the flagstone") is a small village in County Cavan, Ireland on the R154 regional road. Kilnaleck was once the centre of a mining boom when in 1879 some local businessmen and a school headmaster decided to develop the coal that existed nearby. However, the coal was very deep and hard to extract and the mine was forced to close.
