The Linneman Building was a historic commercial building in Lima, Ohio, United States. Located along South Main Street in the city's downtown, it was built in a transitional style of architecture in 1899. A two-story structure, it was constructed of brick arranged in an artistic style. Among its leading architectural features was a pair of large semicircular windows in the center of the building's facade; each window was decorated with a sash of aluminum, and the building was crowned with detailed stone carvings done in the style of the works of Louis Sullivan. In 1982, the building's stonework was rated as being equal to that of the adjacent Dorsey Building and superior to that of all other buildings in the city.
