Earl of Meath is a title in the Peerage of Ireland created in 1627 and held by the head of the Brabazon family. This family descends from Sir Edward Brabazon, who represented County Wicklow in the Irish House of Commons and served as High Sheriff of Staffordshire in 1606. In 1616 he was raised to the Peerage of Ireland as Baron Ardee. He was succeeded by his eldest son, the second Baron. In 1627 he was created Earl of Meath in the Peerage of Ireland, with remainder to his younger brother the Hon. Sir Anthony Brabazon. Lord Meath was succeeded by his son, the second Earl. His grandson, the fourth Earl, served as Lord-Lieutenant of Dublin and of Kildare. He died childless and was succeeded by his younger brother, the fifth Earl. He was also Lord-Lieutenant of Dublin. Lord Meath married the Hon. Juliana, daughter of Patrick Chaworth, 3rd and last Viscount Chaworth (see the Viscount Chaworth).
On his death the titles passed to his eldest son, the sixth Earl. He served as Lord-Lieutenant of Dublin and County Kildare. He died childless and was succeeded by his younger brother, the seventh Earl. His grandson, the ninth Earl, was killed in a duel in 1797. He was succeeded by his younger brother, the tenth Earl. He served as Lord-Lieutenant of Dublin from 1831 to 1851. In 1831 the Chaworth title held by his ancestors was revived when he was created Baron Chaworth, of Eaton Hall in the County of Hereford, in the Peerage of the United Kingdom. This title gave him and his descendants an automatic seat in the House of Lords. His son, the eleventh Earl, sat as MP for Dublin County from 1830 to 1832, and from 1837 to 1841, and was also Lord-Lieutenant of County Wicklow from 1869 to 1887. He was succeeded by his son, the twelfth Earl. He was a politician and philanthropist. His son, the thirteenth Earl, was a Brigadier-General in the Grenadier Guards and the Irish Guards. As of 2014 the titles are held by the latter's grandson, the fifteenth Earl, who succeeded his father in 1998.
The Hon. William Brabazon, of Tara House in County Meath, younger son of the seventh Earl, was the father of Barbara, who married John Moore. Their grandson John Arthur Henry Moore assumed the additional surname of Brabazon and was the father of the aviation pioneer and Conservative politician John Moore-Brabazon, 1st Baron Brabazon of Tara. See the Baron Brabazon of Tara for more information on this branch of the family.
