Mary Tudor (18 March 1496 – 25 June 1533) was Queen of France from 1514 to 1515.

The third daughter of Henry VII of England and Elizabeth of York, she married Louis XII of France in 1514, becoming Queen of France. Louis died the following year with no male heirs, and was succeeded by his cousin, Francis I.

Around this time, Mary resided at the Hôtel de Cluny. Fearing that she would produce a son who could claim the throne, Francis kept her under surveillance, and found her in a romantic relationship with the Duke of Suffolk. The couple married in secret, before being sent to England.
