Crossdoney or Crosdoney (Irish: Cros Domhnaigh, meaning "cross of the church") is a village in County Cavan, Ireland. Situated on the R154 regional road where it terminates at a junction with the R198. Peculiarly, all buildings in the village sit on one side of the road, and this gives rise to the widely used local expression: "All to one side like Crossdoney".
