General John Thomas de Burgh, 13th Earl of Clanricarde, PC (Ire) (English: /dəˈbɜːr ... klænˈrɪkɑːrd/ də-BUR ... klan-RIK-ard; 22 September 1744 – 27 July 1808), styled The Honourable John Thomas de Burgh until 1797, was a British Army officer and politician who served as the governor of Kingston-upon-Hull from 1801 to 1808.

In 1796, he was in command in Corsica under Sir Gilbert Elliot-Murray-Kynynmound as Viceroy of the Anglo-Corsican Kingdom and, with Commodore Horatio Nelson, planned an attack to re-take Leghorn (Livorno) in Tuscany.

In 1800, he was made Earl of Clanricarde (by a second creation) in the Peerage of Ireland, with a remainder, failing male issue of his own, to his daughters Lady Hester Catherine de Burgh (wife of the 2nd Marquess of Sligo) and Lady Emily de Burgh, and the heirs male of their bodies according to priority of birth.

Lord Clanricarde, as he was from December 1797, was elected as one of the 28 original Irish representative peers in 1800, and became a Privy Councillor in 1801.

[6] Lord Clanricarde married Elizabeth (1764–1854), a daughter of Sir Thomas Burke, 1st Baronet, of Marble Hill, County Galway, on 17 March 1799.
