William O'Connor Morris (26 November 1824, Kilkenny – 3 August 1904) was an Irish county court judge and historian.
He graduated there in 1848 after a leave of absence of a year and a half in 1846–1847 due to his family's financial difficulties connected with the Great Famine.
Three years after leaving Oxford, he entered the King's Inns in Dublin as a law student.
In 1863 he was appointed Special Commissioner of Irish Fisheries but was compelled to resign due to a differing opinion with Sir Robert Peel.
