The History of the Decline and Fall of the Roman Empire (sometimes shortened to Fall of the Roman Empire) is a book of history written by the English historian Edward Gibbon. It traces the trajectory of Western civilization (as well as the Islamic and Mongolian conquests) from the height of the Roman Empire to the fall of Byzantium.

The work covers the history of the Roman Empire, Europe, and the Catholic Church from 98 to 1590 and discusses the decline of the Roman Empire in the East and West. Because of its relative objectivity and heavy use of primary sources, unusual at the time, its methodology became a model for later historians. This led to Gibbon being called the first "modern historian of ancient Rome"
