Dudley Edwards was born and brought up in Dublin and educated at University College Dublin (UCD), Girton College, Cambridge, and Wolfson College, Cambridge. Her father was the Irish historian Professor Robert Dudley Edwards. Her brother Owen Dudley Edwards is a historian at the University of Edinburgh.

Her non-fiction books include An Atlas of Irish History, James Connolly, Victor Gollancz: A Biography (winner of the James Tait Black Memorial Prize), The Pursuit of Reason: The Economist 1843–1993, The Faithful Tribe: An Intimate Portrait of the Loyal Institutions (shortlisted for Channel 4/The House Politico's Book of the Year) and Newspapermen: Hugh Cudlipp, Cecil King and the glory days of Fleet Street. Her Patrick Pearse: The Triumph of Failure (winner of the National University of Ireland Prize for Historical Research), first published in 1977, was reissued in 2006 by Irish Academic Press. In 2009 she published Aftermath: The Omagh Bombings and the Families' Pursuit of Justice a book about the civil case that was won on 8 June 2009 against the Omagh bombers. The Faithful Tribe was criticised by Ulster Protestant journalist Susan McKay as "sentimental and blinkered", but the New Statesman contributor Stephen Howe described it as "engrossing and illuminating" and Irish Independent journalist John A. Murphy described it as "enormously readable, entertaining and informative". In 2016 she published The Seven: The Lives and Legacies of the Founding Fathers of the Irish Republic (Oneworld), a re-examination of the Easter Rising, addressing the fundamental questions and myths surrounding Ireland's founding fathers.
