Dundalk Lower (Irish: Dún Dealgan Íochtarach) is a barony in County Louth, Ireland.

Dundalk Lower is named after the town of Dundalk (Irish: Dún Dealgan, "Dalgan's dún").

Dundalk Lower is found in northeast County Louth, making up all of the Cooley Peninsula.

Dundalk Lower is bordered to the west by Dundalk Upper (Irish: Dún Dealgan Uachtarach), and to the northwest by Orior Upper (Irish: Na hOirthir Uachtaracha), County Armagh, and to the northeast by Iveagh Upper, Upper Half (Irish: Uíbh Eachach Uachtarach, An Leath Uachtair), and Mourne (Irish: Múrna, Old Irish: Mughdorna) County Down.

Dundalk Lower was formed from the territory of Fera Lorg, Lorgan, or Lurgin. In Airgíalla, the MacScannlain are found centered here in the parish of Ballymacscanlan. The barony of Dundalk was the ancient home of the Conaille Muirtheimhne. The barony was split in half by 1821.
