John Greville Agard Pocock - 7 March 1924 – 12 December 2023 - was Harry C. Black Professor of History Emeritus at Johns Hopkins University and an Honorary Fellow of St John's College, Cambridge.

Born in England, Pocock spent most of his early life in New Zealand. He earned his PhD in 1952 at The University of Cambridge and returned to New Zealand to teach at Canterbury University and the University of Otago. He moved to the United States in 1966 and he taught at Washington University in St. Louis.

From 1975 to 2011, he taught at Johns Hopkins University in Baltimore. He received a number of honorary doctorates, including Harvard University and Johns Hopkins. A Corresponding Fellow of the British Academy and of the Royal Historical Society, Professor Pocock was also a member of the American Academy of Arts and Sciences and of the American Philosophical Society. He was appointed an Officer of the Order of New Zealand Merit in 2002. Pocock is celebrated not merely as a historian, but as a pioneer of a new type of historical methodology: contextualism, i.e., the study of "texts in context". In the 1960s and early '70s, he, along with Quentin Skinner and John Dunn, united informally to undertake this approach as the "Cambridge School" of the history of political thought. His many seminal works on intellectual history include The Ancient Constitution and the Feudal Law (1957, second edition 1987), Politics, Language and Time (1971), The Machiavellian Moment (1975, second edition 2003), Virtue, Commerce and History (1985), Political Thought and History (2009) and six volumes in an ongoing sequence, initiated in 1999, on Gibbon's Decline and Fall of the Roman Empire, collectively titled Barbarism and Religion.

His beloved wife Felicity Pocock (née Willis-Fleming) died in 2014 aged 83. He is survived by his sons Stephen and Hugh and his grandchildren Henry, Charlotte, Rowan and Jasper.
