Dermot Gleeson SC (born 12 November 1949) is an Irish barrister who served as Attorney General of Ireland from 1994 to 1997.
Educated in Blackrock College, Dublin and University College Dublin. Gleeson holds B.A. and LL.M degrees and qualified as a barrister at the King's Inns, Dublin. His father was a barrister and was later appointed a Circuit Court Judge, and two of his brothers are also barristers. Gleeson was called to the Irish bar in 1970 and first practised law on the Cork Circuit, away from Dublin, Ireland's main legal centre. In the early 1970s Gleeson was a part-time lecturer in Constitutional Law at University College Cork.
Gleeson moved to Dublin when he was appointed a Senior Counsel in 1979, at age 30. He is believed to be the youngest 'silk' appointed in the common law world in the last century, beating noted counsel such as the Australian QC Tony Morriss, who was made a silk at 32.
Gleeson was a leading barrister in Ireland in the 1980s and 1990s before he became a senior government advisor and then a businessman. From 1994–1997, Gleeson was Attorney General of Ireland, serving as chief legal advisor to the government of Taoiseach John Bruton. Gleeson is a Bencher of King's Inns. He is also a visiting fellow at the School of Law at University College Dublin.
