John Perceval, 3rd Earl of Egmont (1738 – 1822) was a British politician.
Perceval served as Member of Parliament for Bridgwater from 1762-1768. Perceval was initially declared re-elected in 1768, but on petition he was judged not to have been duly elected and his opponent, Anne Poulett, was seated in his place. During his period in office Perceval served in William Pitt the Younger's government.
He married Isabella Paulet (d. 8 September 1821), daughter of Lord Nassau Powlett on 4 June 1765. His titles he inherited from his father, John Perceval, 2nd Earl of Egmont upon his death in 1770.
His brother was Spencer Perceval, to date the only Prime Minister of the United Kingdom to have been assassinated.
