Christopher Plunket, 2nd Earl of Fingall and 11th Baron Killeen (died 1649) was an Irish politician and soldier. In 1641 he negotiated with the rebels on behalf of the Old English of the Pale and pushed them to join the rebellion. He fought for the rebels at the siege of Drogheda. He joined the Confederates and fought in its Leinster army, among others at Dungan's Hill. When the Confederates fused in the Royalist Alliance, he fought under James Butler, 1st Duke of Ormond in the Battle of Rathmines where he was wounded and taken prisoner. He died of his wounds two weeks later in captivity at Dublin Castle.
