Blue Ash is a city in Hamilton County, Ohio. An inner suburb of Cincinnati, the population was 12,114 at the time of the 2010 census.


Blue Ash is located at 39°14′50″N 84°22′34″W / 39.24722°N 84.37611°W / 39.24722; -84.37611 (39.247109, -84.376038).

According to the 2010 census, the city has a total area of 7.59 square miles (19.7 km2), of which 7.58 square miles (19.6 km2) (or 99.87%) is land and 0.01 square miles (0.026 km2) (or 0.13%) is water.

Blue Ash can be reached by Interstate 71 to the east, Interstate 275 to the north, and Ronald Reagan Cross County Highway to the south.


The area that is now Blue Ash was settled circa 1791. In 1797, the first settlers built Carpenter's Run Baptist Church out of blue ash logs, giving the area its eventual name.

In the late 19th century, the Cincinnati, Lebanon and Northern Railway provided narrow gauge commuter rail service to Blue Ash.

Blue Ash was the site of Cincinnati–Blue Ash Airport from 1921 to 2012. Originally a private airfield called Grisard Field, it was sold to the City of Cincinnati in 1946, becoming Ohio's first municipal airport. Cincinnati desired to expand the airport for major commercial service through the 1950s, but Blue Ash fought the city by incorporating first as a village in 1955 and then as a city in 1961. Eventually, through Reed Hartman's Community Improvement Corporation, Cincinnati developed the surrounding area as an industrial park and golf course. The airport closed on August 29, 2012, and the property was sold to the City of Blue Ash, which opened Summit Park on the property.

In 1998, Blue Ash was to be the northern end of a proposed 19-mile (31 km) MetroMoves light rail line, but the proposal was rejected by Hamilton County voters.

On April 9, 1999, Blue Ash experienced an F4 tornado that caused four deaths.
