Harmony is an unincorporated community in Caroline County, Maryland, United States.
There is a small country store with one gas pump, a church, a local produce stand, and farmland.
While many of the farmers in the area are of German descent as can be seen in last names such as Mueller, Kraus, Thomas, Steenken, and Worm; they settled after the Civil War, filling the void of the men lost in the war.
The older families of Towers, Todd, and Wyddel were the original settlers who came from England in the early eighteenth century, as can be confirmed from the original patents granted to them one of which is Wyddels Venture, the oldest century farm in the county.
There are many cash crops grown such as sweet corn, cantaloupes, tomatoes and squash.
