Frank Dikötter (; ) is a Dutch historian who specialises in modern China. Dikötter has been Chair Professor of Humanities at the University of Hong Kong since 2006. In ''Patient Zero'' (2003) and ''Narcotic Culture'' (2004), Dikötter argued that the impact of the prohibition of opium on the Chinese people led to greater harm than the effects of the drug itself. Dikötter is the author of ''The People's Trilogy'', which consists of ''Mao's Great Famine'' (2010), ''The Tragedy of Liberation'' (2013), and ''The Cultural Revolution'' (2016), providing an overview of Communist-led China.
