Hugh Roe O'Donnell (Irish: Aodh Ruadh mac Néill Gairbh Ó Domhnaill; c. 1427 – 11 July 1505) was a leading figure in Gaelic Ireland, ruling as king of Tyrconnell in Ulster from 1461 to 1505.

[5] He died on 11 July 1505[6] and was succeeded in Tyrconnell by his son, Sir Aodh Dubh Ó Domhnaill, who was also considered a strong ruler who increased the lineages power into northern Connaught and enjoyed the support of the Crown authorities in Dublin.

Many sheltered bays attracted large numbers of foreign merchants and fishermen exploiting an immensely valuable salmon and herring fishery, which developed during the course of the early sixteenth century into one of the biggest of its kind in europe.
