Edmund Halsey (died 1729), of St. Saviour's, Southwark, Surrey and Stoke Poges, Buckinghamshire, was a British brewer and Whig politician who sat in the House of Commons between 1712 and 1729.
He enjoyed a rags-to-riches career, from working as a ‘miller’s boy’ at St. Albans to becoming the owner of one of the largest breweries in the London area.
He was returned as Whig Member of Parliament for Southwark at the by-election on 12 January 1712, although he actually finished 16 votes behind his opponent, Sir George Mathews.
He was a governor of St Thomas’ Hospital by 1719 and a director of the South Sea Company in 1721, holding both positions for the rest of his life.
Two sons predeceased him and he left an only daughter, Anne, Viscountess Cobham, who inherited the Stoke Poges property.
