The Methodist Mission was the Methodist Episcopal Church's 19th-century conversion efforts in the Pacific Northwest. Local Indigenous cultures were introduced to western culture and Christianity. Superintendent Jason Lee was the principal leader for almost a decade. It was a political and religious effort. Two years after the mission began, the church's Board of Foreign Missions described its intent to reclaim "these wandering savages, who are in a very degraded state, to the blessings of Christianity and civilized life." Alongside the missions founded in the region were several secular operations opened. These were maintained to allow for material independence from the Hudson's Bay Company (HBC), then the preeminent economic entity in the region among European descendants.

Jason Lee was a Canadian Methodist Episcopalian missionary and pioneer in the Pacific Northwest. He was born on a farm near Stanstead, Quebec.
