Maud FitzJohn, Countess of Warwick (c. 1238 – 16/18 April 1301) was an English noblewoman and the eldest daughter of John FitzGeoffrey, Lord of Shere.
Through her daughter, Isabella, Maud was the maternal grandmother of Hugh the younger Despenser, the unpopular favourite of King Edward II of England, who was executed in 1326.
The chronicle of Tintern Abbey in Monmouthshire names Matilda uxor Guidono comitis Warwici as the eldest daughter of Johanni Fitz-Geffrey and Isabella Bygod.
Maud married her first husband, Gerald de Furnivall, Lord of Hallamshire on an unknown date, and had Loretta.
Sometime after his death in 1261, Maud married her second husband, the celebrated soldier, William de Beauchamp, 9th Earl of Warwick.
