James Sinclair (1811 – March 26, 1856) was a trader and explorer with the Hudson's Bay Company (HBC). He twice led large parties of settlers from the Red River Colony to the Columbia River valley. These were both authorized by the HBC as a part of grandiose plans to strengthen British claims in the Oregon boundary dispute.
