She had an elder sister Blanche de Ponthieu (before 1326 – 12 April/May 1387) who became suo jure Countess of Aumale on 16 January 1340 upon the death of their father. Blanche was the wife of Jean V de Harcourt, Count of Harcourt, by whom she had issue.

Her maternal grandparents were Philip of Artois and Blanche of Brittany, also known as Blanche de Bretagne, herself the granddaughter of King Henry III of England and Eleanor of Provence.The seigneury of Épernon was part of her father's inheritance which came into his family about 1256 upon the marriage of his grandmother Laure de Montfort, Dame d'Épernon to the Infante Ferdinand of Castile, Count of Aumale.
On an unknown date sometime before 1351, Jeanne married Jean VI de Vendôme, Count of Vendôme and of Castres, Seigneur de Lézingnan-en-Narbonnois, and de Brétencourt of the House of Montoire. He was the son of Bouchard VI de Vendôme, Count of Vendôme and Alix de Bretagne. He succeeded to his titles in 1354; from that time onward, Jeanne was styled as Countess of Vendôme and of Castres. Jean and Jeanne together had two children:
In 1362, the castle and town of Vendôme were plundered by the Anglo-Gascon troops of Captain Robert Marcault, and Jeanne was taken prisoner. She was later ransomed. In 1367, she ordered that the walls of the castle were to be strengthened, and personally superintended the fortifications.
Upon the death of her husband in February 1364 at Montpellier, Jeanne's son Bouchard became Count of Vendôme and of Castres. When he died in 1371, the titles passed to his infant daughter, Jeanne. Jeanne de Ponthieu acted as regent for her granddaughter from 1371 until the latter's death in 1372. The titles were inherited by Catherine, the only surviving child of Jeanne de Ponthieu. Catherine held the titles jointly with her husband until 1393, then with her second eldest son Louis, Count of Vendôme.
Jeanne died on 30 May 1376.
