Arthur Edward Rory Guinness, 4th Earl of Iveagh, DL (born 25 August 1969), styled Viscount Elveden until 1992, is an Anglo-Irish aristocrat and businessman. Lord Iveagh is a member of the Guinness family.

An Anglo-Irish aristocrat, Iveagh is the son of Benjamin Guinness, 3rd Earl of Iveagh and his wife, Miranda Smiley, and is known to his family and friends as Edward, or Ned, Iveagh.^[1]

Becoming Earl of Iveagh on his father's death on 18 June 1992, when he was aged 23, he was then one of the youngest hereditary peers entitled to sit in the House of Lords, which he regularly attended.^[2] He did not join a political party but sat as a crossbencher.^[1] On 11 November 1999, he was among the majority of the hereditary members who were removed from the Lords by the House of Lords Act 1999.^[2]

On 27 October 2001, Lord Iveagh married the interior designer Clare Hazell at St Andrew's and St Patrick's Church, Elveden, Suffolk.^[3] The couple have two sons, including Arthur, Viscount Elveden (born 2002).

Iveagh lives on the 22,486-acre (91 km²) Elveden Estate in Suffolk, England, which comprises some 2.6% of the county.^[1] The land is occupied as a single arable farm for growing root vegetables, with cereals as a break crop. Approximately 4,000 acres (16 km²) is woodland.^{[citation needed]}

In 1999, Iveagh sold his family's Irish home, Farmleigh and its park, adjacent to the Phoenix Park in Dublin, to the Irish Government for the market price of €29.2m (£18.9m).^[4]
