Joan I (14 January 1273 – 31 March/2 April 1305)^[1] (Basque: Joana, Spanish: Juana) was ruling Queen of Navarre and Countess of Champagne from 1274 until 1305. She was also Queen of France by marriage to King Philip IV. She founded the College of Navarre in Paris in 1305.

Joan never ruled Navarre in person, it being overseen by French governors. Having direct control over the County of Champagne, she raised an army to face the invasion of the county by Henry, Count of Bar, even capturing and imprisoning the count. She died in childbirth in 1305.
