Denis Bowes Daly PC (c. 1745 – 17 December 1821) was an Irish politician.
Daly was the eldest son of Hyacynth Daly of Dalystown, and his cousin Rose Daly of Raford, both of County Galway and educated privately in Dublin and at Trinity College, Dublin.[1]
After serving as High Sheriff of King's County for 1774 he was brought into the Irish parliament by his cousin, Denis Daly of Dunsandle. There he served as MP for Galway Borough from 1776 to 1790 and for King's County from 1790 to 1800. A constant supporter of the Ponsonby's, he voted for catholic relief in 1778 and 1793, the implicit repeal of Poynings' Law in 1782, and for commercial propositions in 1785. He was an agent for Viceroy William Fitzwilliam, 4th Earl Fitzwilliam in attempting to persuade John Beresford to accept a pension, thus leaving office without scandal. Daly strongly opposed the Acts of Union 1800, co-ordinating the factions against the government.
After the acts were passed he represented King's County (1801–02), Galway (1802-05) and County Galway (1805–18). He was sworn of the Irish Privy Council on 7 June 1806.
In 1780 he had married Mary Charlotte Ponsonby, daughter of John Ponsonby and Lady Elizabeth Cavendish, and sister of George Ponsonby. However she died a year after the marriage, after which Daly refused to leave his house for more than twelve months.
