Thomas Blom Hansen (born 22 January 1958 in Frederiksvaerk) is a Danish anthropologist and commentator on religious and political violence in India.
In 2006, he accepted a chair of religion and society at the University of Amsterdam, where he also served as dean of the International School for Humanities and Social Sciences.
He began a study of its local roots and organization in Pune, one of the historical strongholds of the larger Hindu nationalist movement.
Later, he studied the Shiv Sena, a powerful militant movement in Mumbai that played a dominant role in the political and social life for several decades.
Hansen is part of an international research network entitled "The Religious Lives of Migrants," funded by the Ford Foundation and the Social Science Research Council in New York, which explores religious meanings and institutions among international migrants in Kuala Lumpur, London and Johannesburg.
