Blanche of Artois (Basque: Blanka; c. 1248 – 2 May 1302) was Queen of Navarre and Countess of Champagne and Brie during her marriage to Henry I of Navarre. After his death she became regent in the name of their infant daughter, Joan I. She passed on the regency of Navarre to Philip III of France, her cousin and her daughter's prospective father-in-law, but retained the administration of Champagne. She later shared the government of Champagne with her second husband, Edmund, until her daughter reached the age of majority.
