Arthur O'Connor (4 July 1763 – 25 April 1852), was a United Irishman who was active in seeking allies for the Irish cause in England and, in a last constitutional effort to pursue reform, sought to return to the Irish House of Commons, where he had earlier served, in the parliamentary elections of 1796. Arrested on the eve of the 1798 rebellion, in 1802 he went into exile in France where he rose to the rank of general in the army of Napoleon.
