(d. 1665), a puritan opponent of Wentworth and leading anti-Catholic politician with estates in Antrim and London-derry. Clotworthy received a seat in the English Long Parliament in 1640 and appeared as a witness at Wentworth's trial. Rumours about his activities aroused Catholic fears prior to the rising of 1641. He reported the subsequent massacres to the Commons and became an adventurer. His wish to accelerate the reconquest made him an unpopular supporter of peace with the king in 1645–8. Charles II created him Viscount Massereene (1660) when he returned to England to represent adventurer and soldier interests.
