Maximilian O'Dempsey, 3rd Viscount Clanmalier (died 1691) was an Irish aristocrat.
He was the son of Lewis O'Dempsey, 2nd Viscount Clanmalier and succeeded him in 1683. He was of mixed Gaelic and Old English descent. He was a Roman Catholic and a supporter of his fellow Catholic King James II during the Williamite War in Ireland. He was appointed Governor of Queen's County by James and attended the Irish House of Lords in the Patriot Parliament of 1689. [1]
He died in 1691. Although he had been married twice, to Anne Bermingham and Margaret FitzMaurice, he was childless and his position as Clan Chief was inherited by his younger brother, Terence O'Dempsey, who fled to Cheshire, England after the confiscation of the family estates carrying with him the original King Charles 1st Title document. This Terence was the ancestor of James Dempsey of Liverpool, a notable Georgian period merchant and ship owner and General sir Miles Dempsey, who commanded the British 2nd Army at D-Day during WW2.[ citation needed ]

Viscount Clanmalier, in the King's and Queen's County, was a title in the Peerage of Ireland. It was created on 22 December 1631 for Sir Terence O'Dempsey, Sheriff of Queen's County in 1591 who was knighted in 1599. He was made Baron of Phillipstown, in the Queen's County, at the same time, also in the Peerage of Ireland. His grandson, Lewis, the second Viscount, joined the Irish Rebellion of 1641 and was consequently attainted with his titles forfeited. However, in 1662 he was restored to a third of his former estates and presumably to his titles. His son, Maximilian, the third Viscount, was Governor of King's County. It is believed that Terence O'Dempsey, the youngest son of Maximilian fled Ireland with his cousin Sir John Byrne to England. The actual velum title document still exists.
