Joan of Lusignan (1260 – 13 April 1323) was a French noblewoman. She succeeded her uncle, Guy de la Marche, Knight, sometime in the period, 1310/13, as Lady of Couche and Peyrat, but not as Countess of La Marche since after her sister, Yolande's death, it was annexed by Philip IV of France and given as an appanage to Philip's son Charles the Fair. Previously, in 1308, following the death of her brother Guy (or Guiard), Jeanne and her sister Isabelle, as co-heiresses, had sold the county of Angoulême to the King.^[1]

She was married twice. Her first husband was Bernard Ezi III, Lord of Albret, by whom she had two daughters. By her second husband Sir Piers de Geneville, she had another three daughters; the eldest of whom was Joan de Geneville, 2nd Baroness Geneville, wife of Roger Mortimer, 1st Earl of March, the de facto ruler of England from 1327 to 1330.

She is sometimes referred to as Jeanne of Lusignan.

Joan was a younger daughter of Hugh XII of Lusignan, Count of La Marche and Angoulême, lord of Lusignan and Fougères, and Jeanne de Fougères.^{[citation needed]}
