Viscount Clermont, of Clermont in the County of Louth, was a title in the Peerage of Ireland. It was created in 1776 for William Fortescue, 1st Baron Clermont, with special remainder in default of male issue of his own to his brother James Fortescue and the heirs male of his body. He was the son of Thomas Fortescue (1683–1769), an Irish Member of Parliament and a descendant of the prominent and widespread family of Fortescue of Whympston in the parish of Modbury in Devon, England, the earliest Fortescue seat in the British Isles. Of the many branches of the Fortescue family which remained in Devon, that seated at Filleigh inherited in 1721 the ancient title Baron Clinton in the Peerage of England and subsequently obtained new titles in the Peerage of Great Britain of Baron Fortescue (1746), Earl Clinton (1746), Viscount Ebrington (1789) and Earl Fortescue (1789). William Henry Fortescue had already been made Baron Clermont, of Clermont in the County of Louth, in the Peerage of Ireland in 1770, with normal remainder to heirs male, and in 1776 was again made Baron Clermont, of Clermont in the County of Louth, in the Peerage of Ireland, at the same time he was granted the viscountcy, but with special remainder to his brother James Fortescue. By that date it was apparent that he was unlikely to produce his own son and heir, hence the special remainder was granted. In 1777 he was further honoured when he was made Earl of Clermont, in the County of Louth, in the Peerage of Ireland, with normal remainder to heirs male. Lord Clermont died without male issue in 1806 when the barony of 1770 and earldom became extinct. He was succeeded in the barony of 1776 and viscountcy according to the special remainder by his nephew William Fortescue, the 2nd Viscount Clermont and 2nd Baron Clermont, the son of his aforementioned brother James Fortescue. The 2nd Viscount Clermont represented County Louth in both the Irish and British Parliaments and was an Irish Representative Peer. He died unmarried in 1829 when the barony and viscountcy became extinct. The Clermont title was revived in 1852 when Thomas Fortescue was made Baron Clermont. He was a descendant of Chichester Fortescue, brother of William Fortescue, grandfather of the first Earl of Clermont.
