Roger Boyle, 1st Earl of Orrery, 25 April 1621 to 16 October 1679, was an Anglo-Irish soldier and politician. A younger son of the Earl of Cork, the largest landowner in Munster, like many Irish Protestants he supported the Dublin Castle administration during the Irish Confederate Wars, a related conflict of the Wars of the Three Kingdoms.
Boyle was noted for his anti-Catholicism, and consistently opposed concessions to Irish Catholics. A skilled politician, he believed maintaining the Protestant Ascendancy in Ireland required support from the ruling government in London, whatever its composition. As a result, he held senior positions under the Commonwealth and Charles II, following the 1660 Stuart Restoration.
A noted writer on 17th-century warfare, Boyle helped design Charles Fort outside Kinsale. He also produced a number of plays and poems, which were well regarded by contemporaries but have since faded into obscurity.
