John of Fordun (before 1360 – c. 1384) was a Scottish chronicler. It is generally stated that he was born at Fordoun, Mearns. It is certain that he was a secular priest, and that he composed his history in the latter part of the 14th century. It is probable that he was a chaplain in St Machar's Cathedral of Aberdeen.
The work of Fordun is the earliest attempt to write a continuous history of Scotland. Fordun undertook this task because his patriotic zeal was roused by the removal or destruction of many national records by Edward III of England. He travelled across England and Ireland, collecting material for his history.
