Richard G. Wilkinson (Richard Gerald Wilkinson; born 1943) is a British researcher in social inequalities in health and the social determinants of health. He is Professor Emeritus of social epidemiology at the University of Nottingham, having retired in 2008. He is also Honorary Professor at University College London.
He is best known for his 2009 book (with Kate Pickett) The Spirit Level, in which he argues that societies with more a equal distribution of incomes have better health outcomes than ones in which the gap between richest and poorest parts society is greater. His 1996 book Unhealthy Societies: The Affliction of Inequality had made the same argument a decade earlier.
