Miles de Courcy (died c.1720) was an Irish Jacobite politician.
De Courcy was the son of Patrick de Courcy, 13th Baron Kingsale and Mary FitzGerald. A burgess of Kinsale from 1687, in 1689 he was elected as a Member of Parliament for Kinsale in the short-lived Patriot Parliament called by James II of England.[1] During the Williamite War in Ireland, he was a captain in Boiseleau's Regiment of Foot.[2] De Courcy was subsequently attainted, but he was restored to his estates under the Articles of Limerick.
He married Elizabeth Sadleir; their son, Gerald, inherited the title of his cousin, Almeric de Courcy, 23rd Baron Kingsale, in 1720.[3]
