Daniel O'Neill (1920 – March 9, 1974) was a Romantic painter born in Belfast, Ireland.
The son of an electrician, and himself an electrician by trade, O'Neill was largely self-taught, although he briefly attended Belfast College of Art life classes, before working with and studying under fellow Belfast artist Sidney Smith.
He quickly developed an expressionist technique, and strong romanticism, with imagery, often full of pathos, evoking the themes of love, life and death.
A number of works followed on which his reputation largely rests, including Place du Tertre (1949), The Blue Skirt (1949), Knockalla Hills, Donegal (1951) and Birth (1952).
