The Navarrese Company was a company of mercenaries from Navarre and Gascony that was active during the later Middle Ages. The company was formed to fight for Charles II of Navarre against Charles V of France, and the company was organized into a mercenary group in 1366 after peace was made between the two rulers. From the late 14th century to the early 15th century, the company fought in Greece to protect the remnants of the former Latin Empire, and it helped with the organization of the political system of the Morea region before signing a treaty with the Republic of Venice.
