Jefferson Mosier House

The Jefferson Mosier House is a historic house in Mosier, Oregon, United States. Jefferson N. Mosier (1860–1928) first platted the town in 1902 on what had been his father's donation land claim, and tirelessly promoted it for decades after. He built this prominent house in 1904, and remained in residence until his death. It is the only Queen Anne building in Mosier, and features many signature characteristics of the type.

The house was added to the National Register of Historic Places in 1990. By 2006, it had been converted for use as a bed and breakfast inn.
