Lusby is a thriving, unincorporated community located in the southern portion of Calvert County, Maryland. Situated on the scenic peninsula between the Patuxent River and the Chesapeake Bay, Lusby is best known as a bedroom community that offers a rich blend of waterfront living, historical significance, and modern energy production. Though technically a Census-Designated Place (CDP) covering just over three square miles, the broader Lusby area (encompassed by the 20657 ZIP code) is one of the most populated regions in the county.
The area is famous for Calvert Cliffs State Park, a striking stretch of shoreline known worldwide for its fossilized shark teeth and prehistoric marine life dating back to the Miocene epoch. Beyond its natural beauty, Lusby plays a critical role in the region's infrastructure and economy, housing both the Calvert Cliffs Nuclear Power Plant and the Cove Point LNG (liquefied natural gas) terminal.
Today, Lusby balances its rapidly growing residential neighborhoods with a deep appreciation for the Chesapeake Bay lifestyle. It serves as an essential hub for professionals commuting to the nearby Patuxent River Naval Air Station, as well as a peaceful retreat for those drawn to the maritime heritage of Southern Maryland.
