Ballyboughal (Irish: Baile Bachaille), also sometimes Ballyboghil, is a village and district in central Fingal within the historic County Dublin, near the Naul. The name means the town of the staff, and the Bachal Isu was protected in this area until Strongbow moved it to Christ Church, Dublin. It is 4.4km from Oldtown. There was a monastery in Ballyboughal sometime before the arrival of the Anglo-Normans. The Ballyboughal (or Ballyboghil) River flows eastward through the center of the settlement. It has its source at Tobergregan, south of Garristown, and its mouth at the Rogerstown Estuary.
