Charles Blount, 8th Baron Mountjoy, English general and politician, Lord Lieutenant of Ireland (born 1563)

Charles Brooke Blount, 1st Earl of Devonshire, KG, was an English nobleman and soldier who served as Lord Deputy of Ireland under Elizabeth I, and later as Lord Lieutenant of Ireland under James I. He was instrumental in forcing the Irish confederacy's surrender in the Nine Years' War, and he is also known for his scandalous affair with married noblewoman Penelope Rich, whom he later married.

Lord Lieutenant of Ireland, or more formally Lieutenant General and General Governor of Ireland, was the title of the chief governor of Ireland from the Williamite Wars of 1690 until the Partition of Ireland in 1922. This spanned the Kingdom of Ireland (1541–1800) and the United Kingdom of Great Britain and Ireland (1801–1922). The office, under its various names, was often more generally known as the Viceroy, and his wife was known as the vicereine. The government of Ireland in practice was usually in the hands of the Lord Deputy up to the 17th century, and later of the Chief Secretary for Ireland.
