Catherine of Valois (October 27, 1401 – January 3, 1437) is the Queen consort of England from 1420 until 1422.

She is the descendant, consort, and ancestor of kings.

A daughter of Charles VI of France, she marries Henry V of England, and gives birth to his heir Henry VI of England.

Her liaison (and possible secret marriage) with Owen Tudor proves the springboard of that family's fortunes, eventually leading to their grandson's elevation as Henry VII of England.

Catherine's older sister Isabella was queen of England from 1396 until 1399, as the child bride of Richard II.
