Barry Gordon Buzan, FBA, FAcSS (born 28 April 1946) is a British political scientist. He is an Emeritus Professor of International Relations at the London School of Economics and a honorary professor at the University of Copenhagen and Jilin University. Until 2012 he was Montague Burton Professor of International Relations at the LSE. Buzan sketched the Regional Security Complex Theory and is therefore together with Ole Wæver a central figure of the Copenhagen School.

From 1988 to 2002 he was Project Director at the Copenhagen Peace Research Institute (COPRI). From 1995 to 2002 he was research Professor of International Studies at the University of Westminster, and before that Professor of International Studies at the University of Warwick. During 1993 he was visiting professor at the International University of Japan, and in 1997–8 he was Olof Palme Visiting Professor in Sweden.

He was Chairman of the British International Studies Association 1988–90, Vice-President of the (North American) International Studies Association 1993–4, and founding Secretary of the International Studies Coordinating Committee 1994–8. From 1999 to 2011 he was the general coordinator of a project to reconvene the English school of international relations theory, and from 2004 to 2008 he was editor of the European Journal of International Relations. In 1998 he was elected a fellow of the British Academy, and in 2001 he was elected to the Academy of Learned Societies for the Social Sciences.

Buzan defines his interests as:

1. the conceptual and regional aspects of international security;
2. international history, and the evolution of the international system since prehistory;
3. international relations theory, particularly structural realism;
4. international society, and the 'English School' approach to International Relations.

Buzan was a major contributor to the Copenhagen School of political thought, connecting the concept of securitization to the regional security complex theory.^[1]

Buzan's 1983 text People, States and Fear had a significant impact on criticism of the prevailing state-centric views of the international system.^[2] Buzan contended that understandings of national security should be broadened to address systemic concerns involving individuals, states, and the entire international system.^[2] In this view, economic, social, and environmental factors of security should be considered in addition to political and military aspects of security.^[2]

Buzan was born in London, but his family emigrated to Canada in 1954. He holds the citizenships of the United Kingdom and Canada. He attended Kitsilano Secondary School in Vancouver, British Columbia. Buzan is a graduate of the University of British Columbia (1968) where he started an uncompleted master programme. He received his doctorate at the London School of Economics (1973). He describes his political views as social democratic and his religious views as extreme secularist.^[3]

Buzan's wife, Deborah Skinner, is an artist and youngest daughter of psychologist B. F. Skinner.^[4][5] They have no children. His brother was author Tony Buzan, with whom he co-authored The Mind Map Book.^[6]
