George King, 3rd Earl of Kingston

George King, 3rd Earl of Kingston (9 April 1771 – 18 October 1839), styled Viscount Kingsborough from 1797 to 1799, was an Irish nobleman.

He was returned as a Member of the Irish House of Commons for County Roscommon in 1798, vacating the seat in the following year when he succeeded his father to the peerage and briefly taking his seat in the Irish House of Lords before it was abolished in 1800 after the union with Great Britain.

He was created Baron Kingston in the Peerage of the United Kingdom in 1821, thus giving him and his descendants an automatic seat in the UK House of Lords.

[1] In 1823, he demolished the existing Palladian house on the Mitchelstown estate and replaced it with a new castle designed by James and George Richard Pain.

[3] On 5 May 1794, he married Lady Helena, the daughter of Stephen Moore, 1st Earl Mount Cashell.
