The Barony of Auckland exists in both the Peerage of Ireland and the Peerage of Great Britain. The first creation came in 1789 when the then-Postmaster-General William Eden was created Baron Eden in the Peerage of Ireland. In 1793, he was made a Baron in the Peerage of Great Britain and therefore obtained a seat in the House of Lords.
The second Baron, George, was created an Earl in 1839 while he served as Governor-General of India. The Earldom became extinct when he died.
