Owen Connellan (1797 – 4 August 1871) was an Irish scholar who translated the Annals of the Four Masters into English in 1846.
He was born in County Sligo, the son of a farmer who claimed descent from Lóegaire mac Néill, High King of Ireland in the fifth century.
[2] His most important work was Imtheacht na Tromdhaimhe, or, The proceedings of the great Bardic Institution, which relates how Senchán Torpéist recovered the Táin Bó Cúailnge, one of the most famous tales of the Irish bards.
Little notice was taken of the book until he was rash enough to print in the Christian Examiner for September 1833 a long letter on "The Irish Language", ostensibly a critique of Owen Connellan's edition of the Irish prayer-book, but in reality a personal attack upon him and Thady Connellan, a relative.
Owen Connellan replied, as far as the editor of the magazine would allow him, in the October number (pp. 729–732).
