This article is about the English queen. For the Portuguese queen, see Philippa of Lancaster.

Philippa of Hainault (24 June 1314 – 15 August 1369) was Queen of England as the wife of King Edward III. Edward, Duke of Guyenne, her future husband, promised in 1326 to marry her within the following two years. She was married to Edward, first by proxy, when Edward dispatched the Bishop of Coventry "to marry her in his name" in Valenciennes (second city in importance of the county of Hainaut) in October 1327. The marriage was celebrated formally in York Minster on 24 January 1328, some months after Edward's accession to the throne of England. In August 1328, he also fixed his wife's dower.
