Étienne Lucier, né Lussier, (June 9, 1786 – March 8, 1853) was a French-Canadian fur trader active primarily in the Pacific Northwest. He was hired by John Jacob Astor's Pacific Fur Company and sent to the region to help establish Fort Astoria. Later he became a settler in the Willamette Valley. Lucier attended the Champoeg Meetings and was one of few French-Canadians or "Canadiens" to vote for the Provisional Government of Oregon, an American and Canadian civil authority for the valley. He is credited with becoming the first European descendant farmer within the modern state of Oregon.
