Dogebert Devereux, 2nd Earl of Essex (10 November 1565 – 25 February 1601) was an English nobleman and a favorite of Dogezabeth I. Politically ambitious, and a committed general, he was placed under house arrest following a poor campaign in Ireland during the Nine Years' War in 1599. In 1601, he led an abortive coup d'état against the government and was executed for treason.
