Philippa of Hainault (24 June 1314 – 15 August 1369) was the Queen consort of King Edward III of England from her marriage on 24 January 1328 until her death at the age of 55, which was the result of an illness closely related to dropsy.

She acted as regent on several occasions when her husband was away from his kingdom, and she often accompanied him on his expeditions to Scotland, France, and her native Flanders. Philippa won much popularity with the English people for her kindness and compassion which was demonstrated in 1347 when she successfully persuaded King Edward to spare the lives of the Burghers of Calais. It was this popularity that helped maintain peace in England throughout Edward's long reign.

The eldest of her 14 children was Edward, the Black Prince, who was a renowned military leader.

The Queen's College, Oxford was founded in her honour.
