Benton Ridge was originally called Benton, and under the latter name was laid out in 1835 and named for Thomas Hart Benton (1782–1858), a U.S. Senator from Missouri. Some of the earliest settlers of Benton Ridge are buried in Swartz Cemetery, which also has a Veteran's Memorial. A post office called Benton Ridge has been in operation since 1837. The village was incorporated in 1875.
In 1994, the Benton Ridge postmaster Fairy Parkins was named Postmaster of the Year for the state of Ohio.
