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.

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.

Other western explorers with ties to Boucherville include Jacques Denoyon, the family Gaultier de la Verendrye, and Toussaint Charbonneau.

Lucier was assigned to travel overland in an expedition led by Wilson Price Hunt to the Pacific Northwest.

[1] Lucier established a permanent land claim next to the Willamette Fur Post near Champoeg on the French Prairie by 1829.

[1] On his 80 acres (32 ha) farm he raised pigs and hogs, cattle, peaches, and wheat that were enclosed by a split-rail fence.
