Hugh McShane O'Neill was an early modern Irish nobleman and rebel associated with the McShanes of Glenconkeyne and Killetra (modern south County Londonderry). This group was also called the "Wild Clan Shanes of Killetragh" or the "McShane-O'Neills". His parentage is disputed however he is claimed by some as being either a grandson or great-grandson of Conn O'Neill, 1st Earl of Tyrone, and Gearoid Mór Fitzgerald, 8th Earl of Kildare, and of the primary line of the O'Neill of Tyrone clan.
