Stacey Grimaldi (18 October 1790 – 28 March 1863), was an English lawyer and antiquary.
Stacey Grimaldi was descended from the house of Grimaldi: he was the great-grandson of Alexander Grimaldi of Genoa, who quit that city after its bombardment by Louis XIV in 1684, and whose father of the same name had been doge of Genoa in 1671. He was born in the parish of St. James, Westminster, on 18 October 1790, and was the second son of William Grimaldi, miniature-painter, of Albemarle Street, London, by his wife Frances, daughter of Louis Barker of Rochester. Upon the death of his elder brother in 1835 the title of Marquis Grimaldi of Genoa and the claims on the family possessions in Genoa and Monaco became vested in him.
For upwards of forty years he practised as a solicitor in Copthall Court in the city of London. He was eminent as a 'record lawyer,' and was engaged in several important record trials and peerage cases. In 1824 he was elected a fellow of the Society of Antiquaries. In 1834 he was appointed to deliver lectures on the public records at the Law Institution, and in 1853 an auditor of the Incorporated Law Society. He was a frequent contributor to the Gentleman's Magazine from 1813 to 1861. He resided for many years at Maze Hill, Greenwich; latterly at Herndon House, Eastry, Kent, where he died on 28 March 1863. In 1825 he married Mary Ann, daughter of Thomas George Knapp of Haberdashers' Hall and Norwood, Surrey. By her he left six sons and three daughters.
