Laurens Storm van 's Gravesande (12 October 1704 – 14 August 1775) was a Dutch governor of the colonies of Essequibo and Demerara from 1743 to 1772. He turned Demerara in a successful plantation colony, and the borders of Guyana are mainly based on his expeditions into the interior. He is also noted for his treatment of the Amerindians.
