George Augustus Hamilton Chichester, 5th Marquess of Donegall (27 June 1822 – 13 May 1904), styled Earl of Belfast from 1853 until 1899, was an Anglo-Irish soldier and company promoter who became an Irish and British peer, with a seat in the House of Lords.
In his youth he was an officer of the 6th Regiment of Foot by purchase and a director of railway companies. He was made bankrupt in 1866 and died in reduced circumstances, after inheriting his peerages in 1889. After being widowed in 1901 he advertised that he was willing to marry again for £25,000 to be paid to himself and in the last year of his life finally succeeded in gaining a son and heir.
