Isabella of Navarre (1395 – 31 August 1450) was the younger surviving daughter of Charles III of Navarre and his wife Eleanor of Castile. She was a member of the House of Évreux.

Shortly before Isabella's birth, her mother was dealing with problems in Castile, involving her brother John I of Aragon. Eleanor was forced to return to Navarre for her daughter's birth.

Isabella was the sixth of eight children. Her two younger brothers died in childhood, leaving Isabella and her five older sisters. Her sisters included: Joanna (died before inheriting the throne), Blanche (successor of their father) and Beatrix, (married James II, Count of La Marche)

Isabella's maternal grandparents were Henry II of Castile and Juana Manuel of Castile. Her paternal grandparents were Charles II of Navarre and Joan of France, herself daughter of John II of France and Bonne of Bohemia.

Isabella was firstly betrothed to Infante John of Aragon around 1414. Her mother, Queen Eleanor bequeathed her money for the marriage. John later became King of Aragon but broke off his contract with Isabella, in hopes of marrying Joanna II of Naples.

Isabella eventually married on 10 May 1419 John IV of Armagnac. This marriage was John's second marriage, after the death of his first wife Blanche of Brittany, who had left no sons.
