Helmer, Michigan is an unincorporated community in Lakefield Township, Luce County in the U.S. state of Michigan, on the northeast shore of Manistique Lake, approximately 11 miles (18 km) southwest of Newberry.
Rev. Mills of Newberry's Presbyterian church built a parsonage and mission house here in 1881-82. The building served as a mission until 1888 when it was purchased by Gaylord Helmer. Helmer used the building as a store and hotel, which became known as the Helmer House Inn. A post office opened March 19, 1894 with Helmer as the first postmaster. Also in 1894, the house became a stagecoach stop and Helmer added a second structure to accommodate more travelers.
In 1904, Charles and Jeanie Fyvie purchased the Helmer House Inn and store. The post office closed September 30, 1914 and became an Rural Free Delivery (RFD) station. The Fyvie family operated the store and hotel until 1950. The building fell into disrepair until being restored and reopened as a bed and breakfast by Dr. James H. Fyvie in 1981 to commemorate its centennial.
On January 13, 1982 it was listed as a Michigan State Historic Site and in 1983, a historical marker was erected for the site.
