John of Prades

John of Aragon and Foix (Joan de Prades, 1335–1414) was a younger son of Peter IV of Ribagorza and Joanna of Foix, and a grandson of James II of Aragon. In 1358 he became Count of Prades and served as seneschal of Catalonia.

After Martin I's death he was one of the claimants to the Aragonese throne, but at the Compromise of Caspe he won little support. In 1412 he recognized Ferdinand of Antequera as Ferdinand I.
