The historiography of the United Kingdom includes the historical and archival research and writing on the history of the United Kingdom, Great Britain, England, Scotland, Ireland, and Wales. For studies of the overseas empire see historiography of the British Empire.

The historiography of the British Empire refers to the studies, sources, critical methods and interpretations used by scholars to develop a history of the British Empire. Historians and their ideas are the main focus here; specific lands and historical dates and episodes are covered in the article on the British Empire. Scholars have long studied the Empire, looking at the causes for its formation, its relations to the French and other empires, and the kinds of people who became imperialists or anti-imperialists, together with their mindsets. The history of the breakdown of the Empire has attracted scholars of the histories of the United States, the British Raj, and the African colonies. John Darwin (2013) identifies four imperial goals: colonising, civilising, converting, and commerce.
