Elmdale is an unincorporated community in Coal Creek Township, Montgomery County, in the U.S. state of Indiana.
Elmdale was originally known under the name Boston Store.[2] The name was later changed to Elmdale, likely due to the abundance of elm trees in the area.[3]
A post office was established under the name Boston Store in 1866, was renamed Elmdale in 1882, and remained in operation until it was discontinued in 1905.[4]
