Dermot Seymour (b. 1956, Belfast, Northern Ireland) is a Northern Irish artist. He has been described as "a social realist, exploring the anxiety, bewilderment and absurdity of the situation in Northern Ireland and representing it with definite imagery but in an oblique and obscure way". His social realist approach towards Northern Irish politics frequently involves a juxtaposition of images within the Irish landscape, particularly livestock, and religious and military symbols. He lives in County Mayo and is a member of Aosdána.
In 1998, he and painter Martin Gale, each produced a series of landscapes on opposite sides of the Irish border as part of Fair to Mizen, a project organised and exhibited by the Boathouse Gallery in Cork. His work has been included in many exhibitions, including On the Balcony of the Nation which toured the USA during the early 1990s, The Fifth Province – Some New Art from Ireland which toured Canada from 1991 to 1993 and In a State, Kilmainham Gaol, Dublin. He has had solo shows in Belfast, New York, Berlin and Dublin, as well as in Ireland almost every year since 1981, including at the Orchard Gallery, Derry (2000), Kevin Kavanagh Gallery, Dublin (2000 and 2001), Monghan Museum (1999), Logan Gallery, Galway (1999) and the Galway Arts Centre (2002).
