Charles Vancouver (c. 1756 – c. 1815) was an Anglo-American agricultural writer.
He was baptised in a Dutch family at King's Lynn, Norfolk in November 1756, and was an elder brother of George Vancouver. He learned farming in Norfolk, and then was found, around 1776, a post in Ireland working for Lord Shelburne by Arthur Young, at Rahan. He worked there on bog drainage, and during the 1780s took on related reclamation work in Kentucky. Kentucky was being settled at this time by westward migration, and Vancouver had a large holding (53,000 acres) there.
In 1789 Vancouver was trying to establish a settlement on the Big Sandy River, where he had 15,000 acres from 1785. The plan encountered resistance from Native Americans, who (by the account of John Hanks who accompanied Vancouver) stole the party's horses. Vancouver was hoping the intended road from Staunton, Virginia to Lexington, Kentucky would open up the area, and he went back east to lay in stores. But he also lost financially in schemes of James Wilkinson. The trial settlement, around where Louisa, Kentucky now is, lasted to April 1790. Vancouver returned to Sussex in England. A plan he had for exploring the Nootka Sound via an overland route was intended to be put to Sir Joseph Banks through Thomas Martyn.
On the establishment of the Board of Agriculture in 1793, Vancouver was engaged by Sir John Sinclair to write reports on the state of agriculture in some of the English counties. Maria Josepha Holroyd wrote of him in July 1795 as a sensible well-informed man, who had visited several countries.
