Jane Popincourt (died after 1516), was a French maid-of-honour at the royal court of Louis XII and later of Francis I. For around twelve years, she had a position at the English court, first in the reign of Henry VII, as a distinguished tutor engaged to teach French to the Princesses Margaret and Mary; and later in 1509, on the accession of Henry VIII, she was appointed a maid-of-honour to his wife, Catherine of Aragon. In 1514 there were rumors that Jane had become the King's mistress.
