Steiner was a small farming settlement in what is now Frenchtown Charter Township, Monroe County in the U.S. state of Michigan. It was situated at the intersection of the Norfolk Southern Railway and Steiner Road at 41°59′20″N 83°23′15″W / 41.98889°N 83.38750°W / 41.98889; -83.38750Coordinates: 41°59′20″N 83°23′15″W / 41.98889°N 83.38750°W / 41.98889; -83.38750.
It was a station on the Pere Marquette Railroad founded by and named for William Steiner in 1873. A post office opened on September 7, 1886 with John Kohler as the first postmaster. The office closed on July 31, 1925.
The general store and other structures, located between Laduke Roads and the railroad tracks were destroyed in a fire in early 1960s. An elderly lady and her (niece/grandchild) perished in the fire. There was a significant delay in the arrival of rescuers, as the closest fire department was located six miles south, in Monroe. Local anger among area residents after the "Steiner Fire" led to the formation of the Frenchtown Township Volunteer Fire Department.
The sawmill still stands in the same location today. It and a basket factory were operated by the Edgar Calkins family. Few obvious signs remain today of this town except a cluster of several pre-1900 houses, the saw-mill adjoining the railroad tracks, and the road name. Steiner is now one of the lost cities, towns, and counties of Michigan
