Earl of Aldborough, of the Palatinate of Upper Ormond, was a title in the Peerage of Ireland. It was created on 9 February 1777, along with the courtesy title of Viscount Amiens, for John Stratford, 1st Viscount Aldborough, a descendant of the English Stratford family. He had already been created Baron Baltinglass, of Baltinglass, in the County of Wicklow, on 21 May 1763, and Viscount Aldborough, of the Palatinate of Upper Ormond, on 22 July 1776. These titles were also in the Peerage of Ireland. Three of his sons, the second, third and fourth Earls, all succeeded in the titles. They became extinct on the death of the latter's grandson, the sixth Earl, in 1875.
