John Vaughan, 3rd Earl of Lisburne, known as the Honourable John Vaughan until 1820, was a British soldier and Member of Parliament.
Lisburne was the younger son of Wilmot Vaughan, 1st Earl of Lisburne.
He served in the Army, transferring from the 87th Foot to the 58th Foot as a Captain in 1795, and being promoted to Major the next month and Lieutenant-Colonel later the same year. He also represented Cardigan in the House of Commons from 1796 to 1818. In 1820 he succeeded his half-brother in the earldom, but as this was an Irish peerage it did not entitle him to a seat in the House of Lords.
Lord Lisburne married Lucy, daughter of William Courtenay, 2nd Viscount Courtenay, in 1798.
