Leonard Eric Cottrell (21 May 1913 – 6 October 1974) was a British author and journalist.
The majority of his books were popularisations of the archaeology of ancient Egypt.
His book about the Carthaginian general, Hannibal: Enemy of Rome, is notable in its preparation: Cottrell traveled the ostensible path Hannibal took across the Alps into the Po River valley and incorporated his personal findings with his research in the book's narrative.
