The Nampa Department Store in Nampa, Idaho, is a 2-story, brick and stone commercial building designed by Tourtellotte and Hummel and completed in 1910. A 3-story building for the site had been ordered by Falk Mercantile Company, but when the site was developed, Leo Falk along with investor E.H. Dewey scaled back the design and opened the Nampa Department Store, built by contractor G.H. Rush. The building was added to the National Register of Historic Places in 1982.
