A Scottish chronicler; lived in the 14th century; was a canon of Aberdeen Cathedral, and wrote a chronicle of Scottish history, bringing the story up to 1153; materials for further volumes, which he left, were utilised by Walter Bower, an abbot of Inchcolm, in the Forth, who extended the account to 1437, but often tampered with Fordun's narrative; the work is the chief authority in Scottish history up to the time it treats of.
