Mount Carmel is a census-designated place (CDP) in Union Township, Clermont County, Ohio, United States.

In 1788 surveyor John Obannon and his team came in this mostly unsettled area to prepare for building and developing new homes and businesses.

A pioneer from New Jersey, John Rose who was one of the first to settle there in 1796, is actually considered the father of Mt.

The only historical sign of his presence today is a very small graveyard where he is buried, going down Rose Hill entering Hamilton County.

Carmel and surrounding area took advantage of this and grape arbors were popping up throughout Union Township contributing to the distinction of the state leading the country in wine production by 1860.

A post office was established in 1887 however it was being built outside the village limits so East Mt Carmel was created so it could take advantage of the benefits.

By the twentieth century the Summerside and the nearby Glen Este post offices were both closed and were moved to Newtown, farther west.

It is bordered on the north by Summerside and on the west by Dry Run in Anderson Township, Hamilton County.
