The Congress of Arras was a diplomatic congregation established at Arras in the summer of 1435 during the Hundred Years' War, between representatives of England, France and Burgundy. It was the first negotiation since the Treaty of Troyes and replaced the fifteen-year agreement between Burgundy and England that would have seen the dynasty of Henry V inherit the French crown. Historian Richard Vaughan has called it "Europe's first real peace congress."

Philip III the Good ruled as Duke of Burgundy from 1419 until his death in 1467. He was a member of a cadet line of the Valois dynasty, to which all 15th-century kings of France belonged. During his reign, the Burgundian State reached the apex of its prosperity and prestige, and became a leading centre of the arts.
