The Brumback Library is a historic public library in the city of Van Wert, Ohio, United States. Opened at the beginning of the twentieth century in order to serve all residents of Van Wert County, it occupies an architecturally prominent building by David L. Stine, which was constructed with funds donated by a local businessman. The building has been named a historic site, partly because of its place as the first public library in the United States to serve an entire county.
