Joan of Navarre (1382 - July 1413, in Béarn) also known as Jeanne d'Évreux or Joanna was the heir to the throne of Navarre in 1402-1413, and regent of Navarre in the absence of her father on several occasions. She was the eldest child of Charles III of Navarre by his wife Eleanor, daughter of Henry II of Castile.

Joan was a member of the French House of Évreux, she was an elder sister to Blanche I of Navarre, Beatrix, Countess of La Marche and Isabella, Countess of Armagnac.

Joan was originally betrothed in 1401 to Martin I of Sicily, he was widower of Maria of Sicily, who had not given him surviving children. Plans were however changed and Martin married Joan's sister Blanche. Joan herself married at Olite on 12 November 1402 to John I, Count of Foix. The couple were married for eleven years but failed to produce any children.

A month after her wedding, Joan was recognized as heiress to the throne of Navarre at Olite on 3 December 1402; this was after the death of her only surviving brother Louis. She governed Navarre in the name of her parents during their absences abroad.

Joan died at Béarn in July 1413, childless. This meant her younger sister Blanche was made heiress to the throne of Navarre, who succeeded on the 8 September 1425.
