(26 June 1644 N.S.) – 30 June 1670) was the youngest daughter of King Charles I of England, Scotland and Ireland and his wife, Henrietta Maria of France.
Fleeing England with her governess at the age of three, she moved to the court of her first cousin Louis XIV of France, where she was known as Minette.
Henrietta was instrumental in negotiating the Secret Treaty of Dover, in June 1670 – early in the same month as her unexpected death.
Jacobite claims to the throne of Great Britain following the death of Henry Benedict Stuart descend from her through her daughter Anne Marie, Queen of Sardinia.
