Beatrice A. de Graaf (born 19 April 1976) is a Dutch history professor at the Faculty of Humanities at Utrecht University.

In 2007 she transferred to Leiden University, where she co-founded the Centre for Terrorism and Counterterrorism (CTC), attached to The Hague campus.

In February 2014 she returned to Utrecht University, where she holds the chair entitled 'History of International Relations & Global Governance'.

[3] As a historian, De Graaf puts security and counterterrorism in a historical context and aims to not only target an international-scientific audience but also contribute to a deeper understanding of these phenomena with her public books.

[5] De Graaf's overarching research theme is the history of security and (counter)terrorism since the nineteenth century.

In 2018 she discovered evidence in Berlin's archives that pointed to Queen Wilhelmina's involvement in the preparations for Emperor William II's arrival in the Netherlands, in November 1918.

[13] Her book Tegen terreur was translated to English in 2020 by the Cambridge University Press as Fighting Terror after Napoleon.

[15] De Graaf was a Visiting Fellow at St Catherine's College and the History Faculty of the University of Cambridge in 2016.

[18][19] Another Fellowship De Graaf hold is at the Center for Advanced Security, Strategic and Integration Studies (CASSIS) of the University of Bonn.
