Joan of Navarre

Joan of Navarre (c. 1326–1387) was the eldest child of King Philip III and Queen Joan II of Navarre. At her parents' accession in 1328 she became heir presumptive to the Navarrese crown, and in 1333 she was betrothed to Peter, heir to Aragon.

The marriage never took place: she was replaced by her younger sister Maria, renounced her succession rights, and in 1337 was veiled as a Poor Clare at the Abbey of Longchamp. She died in the convent in 1387.
