John Skeffington, 2nd Viscount Massereene (December 1632 – 21 June 1695) was an Anglo-Irish politician, official, and peer.
[4] He was a justice of the peace in Antrim, but was removed from the commission in 1663 in the aftermath of Colonel Thomas Blood's foiled plot to install a Presbyterian administration in Ireland.
[1] In 1680, Skeffington was appointed captain of Lough Neagh, in part owing to his expenditure in improving the fortifications at Antrim Castle.
James II of England excluded Skeffington from the Irish Privy Council upon his accession in 1685.
After time in Derry and Scotland, he was in London by September 1689 where he was where he was one of a committee chosen by Irish Protestant exiles to represent their concerns to the English Williamite government.
