Maurice Roche, 8th Viscount Fermoy (1593–1670) was an magnate and soldier in southern Ireland, and a politician of the Irish Catholic Confederation. He joined the rebels in the Irish Rebellion of 1641 in January 1642, early for Munster, by besieging Richard Boyle, 1st Earl of Cork, a Protestant, in Youghal. He fought for the Confederates in the Irish Confederate Wars and sat on three of their Supreme Councils. He fought against the Parliamentarians in the Cromwellian conquest of Ireland and was excluded from pardon at the surrender in 1652. At the restoration of the monarchy in 1660 he recovered his title but not his lands.
