The Most Hon. Henry Vivien Pierpont Conyngham, 8th Marquess Conyngham (born 23 May 1951), is an Anglo-Irish nobleman who holds a title in the Peerage of Ireland. He is also a former politician.
Styled Viscount Slane until 1974 and Earl of Mount Charles from 1974 until 2009, he succeeded his father in the marquessate in March 2009, although in the Republic of Ireland he is often (and erroneously) still referred to as 'Henry Mountcharles'. The Marquess Conyngham has a high profile in Ireland with a weekly column in the Irish Daily Mirror. He is often termed 'the rock and roll aristocrat' or 'the rock and roll peer' owing to his very successful series of rock concerts from 1981, held in the natural amphitheatre of the grounds of Slane Castle. These have included The Rolling Stones, Thin Lizzy, Queen, U2, Bob Dylan, Bruce Springsteen, David Bowie, Guns N' Roses, Oasis and Madonna. Lord Conyngham received the Industry Award at the 2010 Meteor Awards. In his autobiography Public Space–Private Life: A Decade at Slane Castle, he described his business career and the challenges of being an Anglo-Irish peer in modern Ireland, and how being Anglo-Irish has gradually become more accepted
