Manus O'Donnell (Irish: Maghnas Ó Domhnaill or Manus Ó Domhnaill; 1490 – 9 February 1563) was a Gaelic Irish lord and King of Tyrconnell. After his father Hugh Dubh's death in 1537, Manus succeeded as Tyrconnell's ruler. In 1555 he was imprisoned and deposed by his son Calvagh, who effectively took over the kingdom's leadership. Manus died during his imprisonment in Lifford.
