Paramount-Long Meadow is a census-designated place (CDP) in Washington County, Maryland, United States.

According to the United States Census Bureau, the CDP has a total area of 2.8 square miles (7.3 km2), all land.

The region of Washington County Maryland known today as Long Meadow was originally a large mostly level area covering close to twenty square-miles of agriculturally desirable land west of Antietam Creek.

One of the earliest transportation routes through the colony passed near this region, crossing the upper branches of Antietam Creek before turning southwest.

This was a route preferred by many of the early German and Swiss immigrant settlers to the Hagerstown area from central Pennsylvania.
