Viscount Monck, of Ballytrammon in the County of Wexford, is a title in the Peerage of Ireland. It was created in 1801 for Charles Monck, 1st Baron Monck. He had already been created Baron Monck, of Ballytrammon in the County of Wexford, in 1797, also in the Peerage of Ireland. His eldest son, the second Viscount, was in 1822 created Earl of Rathdowne in the Peerage of Ireland. However, this title became extinct on his death, while he was succeeded in the other titles by his younger brother, the third Viscount. The latter's son, the fourth Viscount, served as the 1st Governor General of Canada. In 1866, he was given the title Baron Monck, of Ballytrammon in the County of Wexford, in the Peerage of the United Kingdom. This title gave the viscounts a seat in the Westminster House of Lords until the passing of the House of Lords Act 1999. As of 2012[update] the titles are held by his great-great-grandson, the seventh Viscount, who succeeded his father in 1982. He does not use his titles.
