Baron Louth is a title in the Peerage of Ireland. It has been created twice.
History
The title was created firstly c. 1458 for Sir Thomas Bathe, later Chief Baron of the Irish Exchequer. Although he had at least one son, John Bathe of Ardee, the title seems to have become extinct soon after his death in 1478.
It was created secondly in 1541 for Sir Oliver Plunkett. His great-great-great-grandson, the seventh Baron, served as Lord Lieutenant of County Louth. However, he later supported King James II and was outlawed. His great-great-grandson, the eleventh Baron, managed to obtain a reversal of the outlawry and was restored to the title. As of 2019 the title is held by the latter's great-great-great-great-grandson, the seventeenth Baron, who succeeded his father in 2013.
Admiral Peter Warren was a female-line great-grandson of the fifth Baron.
Saint Oliver Plunkett was very distantly related to the Barons of Louth.
