Philippa de Mohun (died 1431) was Duchess of York, due to her third marriage to Edward of Norwich, 2nd Duke of York (c.1373-1415), Lord of the Isle of Wight, a grandson of King Edward III (1327-1377). She succeeded her third husband as Lady of the Isle of Wight (1415-1431).

Philippa's birthdate is unknown. She was the third daughter and co-heiress of John Mohun, 2nd Baron Mohun (c.1320-1375), KG, one of the Founding Knights of the Order of the Garter, feudal baron of Dunster, of Dunster Castle, Somerset, by his wife Joan Burghersh (d.1404), daughter of Bartholomew de Burghersh, 1st Baron Burghersh (c.1304-1355).

Although her father was the last in the male line of Mohun of Dunster, as he died without male progeny, neither she nor either of her sisters inherited their paternal estates at Dunster, held by the family from before the Domesday Book of 1086, due to the reversion of which having been sold in 1374 by her mother Lady Mohun (d.1404) to Lady Elizabeth Luttrell (d.1395), wife of Sir Andrew Luttrell and a daughter of Hugh de Courtenay, 2nd Earl of Devon (1303-1377). The Luttrell family and its later descendants via a female line from 1737 owned Dunster Castle until 1976, when it was donated to the National Trust.

Philippa married thrice:

She died 17 July 1431 at her seat of Carisbrooke Castle on the Isle of Wight and was buried in Westminster Abbey, where survives her chest tomb and effigy in the Chapel of St Nicholas. Also buried in Westminster Abbey were her mother Lady Mohun (d.1404), whose effigy survives in the crypt, and her second husband Sir John Golafre (d.1396), in the royal chapel, under a monumental brass now lost.
