Admiral George James Perceval, 6th Earl of Egmont (14 March 1794 – 2 August 1874), known as the Lord Arden between 1840 and 1841, was a British naval commander and Tory politician.
Egmont left Harrow school and was commissioned into the Royal Navy as a powder monkey in August 1805 and fought in HMS Orion in the Battle of Trafalgar the same year, aged eleven. During the Bombardment of Algiers in 1816 he commanded HMS Infernal. He was promoted to rear-admiral on 27 August 1851, to vice-admiral in 1857 and to admiral in 1863.
Egmont was returned to Parliament as one of two representatives for Surrey West in 1837, a seat he held until 1840. The latter year he succeeded his father in the barony of Arden and entered the House of Lords. The following year he also succeeded his half-first cousin once removed, Henry, as sixth Earl of Egmont.
The wills of the 4th and 5th Earls of Egmont were not proven until 1857, after the death of the family solicitor Sir Edward Tierney, by Tierney's son-in-law Sir William Darell. The 6th Earl contested the 5th Earl's will in 1863, on the grounds that Tierney had taken advantage of the 5th Earl's drunkenness to provide a misleading valuation of the estates which influenced the drafting of the will. The 6th Earl ultimately settled out of court with Darell, paying £125,000 for the return of the family estates in Churchtown, County Cork; Tierney and his heirs had realized an estimated £300,000 for their stewardship.
