|Earl of Kingston|
|Died||17 April 1799|
Robert King, 2nd Earl of Kingston (1754 – 17 April 1799) was an Anglo-Irish peer. He was styled Viscount Kingsborough between 1768 and 1797.
He was the eldest surviving son of Edward King, 1st Earl of Kingston and Jane Caulfeild. From 1767 to 1768 he was educated at Eton College. He sat in the Irish House of Commons as the Member of Parliament for Boyle from 1776 to 1783, and for Cork County between 1783 and 1797, and served as a Governor of County Cork in 1789. In 1797 he succeeded to his father's titles and assumed his seat in the Irish House of Lords. Between 1797 and his death he was Custos Rotulorum of Roscommon.
On 18 May 1798, he was tried by his peers in the Irish House of Lords after allegedly murdering his brother-in-law Colonel Henry Gerald FitzGerald. FitzGerald was a married man who eloped with King's daughter Mary Elizabeth. With public sympathy on King's side and with considerable publicity, he was tried by his peers. He was acquitted as after three summonses no witnesses came forward. After a short conferee the Lords Temporal returned to the House of Commons and delivered the verdict 'not guilty'. The Lord Chancellor pronounced the verdict, broke his wand and dismissed the assembly.
