Walter Map (Latin: Gualterius Mappus; 1130 – c. 1210) was a medieval writer. He wrote De nugis curialium, which takes the form of a series of anecdotes of people and places, offering insights on the history of his time.
Map was a courtier of King Henry II of England, who sent him on missions to Louis VII of France and to Pope Alexander III. He became the archdeacon of Oxford in 1196.
