Glen Este is an unincorporated area of Union Township, in Clermont County, Ohio.
Glen Este, Ohio is named for early resident David K. Este, who owned a farm near the intersection of Glen Este-Withamsville Road and the railroad tracks, now State Route 32. He was an officer of the Cincinnati, Georgetown and Portsmouth Railroad and had a combination station and post office established on his land. The main road in town ran through the area of Donnell's Trace now old State Route 74, passing through a glen, hence the name.
The Glen Este post office was established in July 1878 with an insignificant sign on the door that read: "The Eastgate to Cincinnati". One hundred years later, the nickname Eastgate came to be a regional name for the area around Glen Este. The once thriving downtown district on the Cincinnati Batavia Pike, Old State Route 74 has since shifted somewhat to the Eastgate Shopping district near Interstate 275.
Glen Este is split with two ZIP codes; the west side uses Cincinnati addresses and has a zipcode of 45245, while to the east of Clermont Lane, Batavia addresses begin, using 45103.
The community is also home to Glen Este High School. Glen Este High School and Amelia High School, will become West Clermont High School for the beginning of the 2017 school Year. It will be located at the corner of Clough Pike and Bach Buxton Rd.
Some of the businesses that were big from the 1940s through the 1970s were, Micky McGuire's General Store, Charlie McGuire's gas station and garage,Maurice's Grocery Store,Flick's Pony Keg, Pearl's Beauty Shop, which was owned by Willard and Pearl Pitman, and Tom Clepper Construction, who built most of the ranch-style slab homes in the area. This small community actually had four barber shops at one time, of which some are still in existence. One of the oldest remaining homes in town is the Jackson estate, still owned by the family as well as one of the county's largest lake, Jackson's Lake. Next to the lake is a log cabin that has been operating as a tavern under many different names for many different owners for over a hundred years. Native American arrow heads have been found embedded in the construction. Newer homes with boat docks were built surrounding the lake.
