Samuel Johannes Holland (1728 – 28 December 1801) was a Dutch-born Royal Engineer and first Surveyor General of British North America.
In 1754, having possibly made contact with the Duke of Richmond and leaving his wife behind in the Netherlands, Holland emigrated to England to seek advancement under the British flag.
In 1756, Holland, probably with Richmond's aid, became a lieutenant in the Royal Americans, coming to British North America where he would spend the rest of his life.
In 1757, during the French and Indian Wars, he was promoted Captain lieutenant and assigned to reconnoitre Fort Carillon, near Ticonderoga, New York, but in early 1758, he was transferred as assistant engineer to the expedition against Louisbourg.
There, Holland made surveys of the surrounding area and prepared plans and gave engineering advice under the command of Brigadier-General James Wolfe.
Holland was later employed in surveying the settled parts of the Saint Lawrence River Valley and in drawing up new plans for a citadel in Quebec after the French siege was lifted.
Holland arrived in October 1764 on Isle Saint-Jean (now Prince Edward Island)), whose territory was ceded to Britain under the Treaty of Paris (1763).
