Jean Henri Becays Ferrand or Jean Marie Begais Ferrand de la Caussade (10 September 1736 – 28 November 1805) became a French general officer early in the French Revolutionary Wars and led troops during two early actions.

From a noble family, he was enrolled in the French Royal Army as an officer in the Normandie Infantry Regiment.

At the age of ten, he fought at Lauffeld and Bergen op Zoom in the War of the Austrian Succession.

Ordered by his turncoat superior Charles François Dumouriez to surrender Condé-sur-l'Escaut and Valenciennes, Ferrand refused to carry out his instructions.

After the two-month long Siege of Valenciennes, he surrendered the city to Prince Frederick, Duke of York and Albany.
