John of Gaunt's chevauchée of 1373 was an English military raid at the end of the second period of the Hundred Years' War by John of Gaunt, Duke of Lancaster, from his departure from Calais in August 1373 to his arrival at Bordeaux at the end of December 1373.

With more than 1,500 km (930 mi) covered, it is the longest of the chevauchées organised by the English on the continent. Despite the devastation caused, it was a failure for the English crown because of the weak military and political results, and the enormous losses.
