Fort Langley National Historic Site

Fort Langley National Historic Site, commonly shortened to Fort Langley, is a former fur trading post of the Hudson's Bay Company in the community of Fort Langley of Langley, British Columbia, Canada. The national historic site sits above the banks of the Bedford Channel across McMillan Island. The national historic site contains a visitor centre and a largely reconstructed trading post that contains ten structures surrounded by wooden palisades.

Fort Langley was initially established in 1827 in present-day Derby. The fort's operations were later relocated to present-day Langley with the new fort completed in 1839. However, the new fort would be rebuilt in the following year, after a fire ravaged the trading post. The fort continued to see use by the Hudson's Bay Company until 1886, when the company ceased to operate the site as a trading post.
