Jacqueline (Dutch: Jacoba; French: Jacqueline; German: Jakobäa; 15 July 1401 – 8 October 1436), of the House of Wittelsbach, was a noblewoman who ruled the counties of Holland, Zeeland and Hainaut in the Low Countries from 1417 to 1433. She was also Dauphine of France for a short time between 1415 and 1417 and Duchess of Gloucester in the 1420s, if her marriage to Humphrey, Duke of Gloucester, is accepted as valid.

Jacqueline was born in Le Quesnoy and from her birth she was referred to as "of Holland", indicating that she was the heiress of her father's estates.

Jacqueline was the last Wittelsbach ruler of Hainaut and Holland. Following her death, her estates passed into the inheritance of Philip the Good, Duke of Burgundy.
