Lieutenant-General Patrick Purcell of Croagh (died 1651) was an Irish soldier. In his youth he fought in Germany during the Thirty Years' War. Back in Ireland he joined the Irish Rebellion of 1641 in 1642 when it reached Munster. He commanded units of the Confederate Munster Army, or precursors and successors of it, from 1642 to 1651 under their successive commanders-in-chief, Viscount Mountgarret, General Garret Barry, Viscount Muskerry, the Earl of Castlehaven, the Marquess of Ormond, and finally Hugh Dubh O'Neill. In 1651 at the surrender of Limerick to the Parliamentarians, he was excepted from pardon and executed by Henry Ireton.
