Paul Anthony Elliott Bew, Baron Bew (born 22 January 1950) is an historian and life peer. He has worked at Queen's University Belfast since 1979, and is currently Professor of Irish Politics, a position he has held since 1991.
Bew was born in Belfast. He attended Campbell College, Belfast before studying for his BA and PhD at Pembroke College, Cambridge. His first book, Land and the National Question in Ireland, 1858–82 was a revisionist study that challenged nationalist historiography by examining the clash between landowners and tenants as well as the conflict between large and small tenants. His third book, a short study of Charles Stewart Parnell, challenged some of the arguments of the award-winning biography of Parnell by F. S. L. Lyons, though Lyons, one of the "doyens" of modern Irish history, acknowledged the young historian's arguments by stating that "Nothing Dr Bew writes is without interest." Bew's central thesis is that Parnell was a fundamentally conservative figure whose ultimate aim was to secure a continuing position of leadership for the Protestant gentry in a Home Rule Ireland.
In 2007, Oxford University Press published Bew's Ireland: The Politics of Enmity 1789–2006, which forms part of the Oxford History of Modern Europe series. The book received positive reviews.
Bew was also involved in the project by Boston College to record interviews by former participants in the Irish "Troubles", including former republican and loyalist paramilitaries. In 2014, Gerry Adams criticised Bew's handling of the Boston College project, as well as the journalist Ed Moloney and the former IRA volunteer Anthony McIntyre.  Adams claimed Bew had deliberately chosen Moloney and McIntyre because they were unsympathetic to Adams.   Bew expressed regret over the closure of the project, and stated further oral history projects of the Troubles were now "under a cloud". 
Bew's political stance has changed over the years. In a 2004 interview for The Guardian, he stated that "While my language was more obviously leftwing in the 1970s than today, that sympathy has always been there". As a young man, Bew participated in the People's Democracy marches. Bew was briefly a member of a group called the Workers' Association, which advocated the Two Nations Theory of Northern Ireland. Bew was also a member of the Workers' Party of Ireland.
From 1991-93 he served as President of The Irish Association for Cultural, Economic and Social Relations.
Later, Bew served as an adviser to David Trimble. Trimble and Bew are both signatories to the statement of principles of the Henry Jackson Society, which has been characterised as a neoconservative organisation.
Bew's contributions to the Good Friday Agreement process were acknowledged with an appointment to the House of Lords as a life peer in February 2007. He was created Baron Bew, of Donegore in the County of Antrim on 26 March 2007, and sits as a crossbencher.
Lord Bew was appointed Chair Committee on Standards in Public Life, an advisory non-departmental public body of the United Kingdom Government, on 1 September 2013. His term is scheduled to end on 31 August 2018. 
Bew is married to Greta Jones, a history professor at the University of Ulster, with whom he has one son, John Bew, who is professor of history at the Department of War Studies, King's College London.
