Lusby is a census-designated place (CDP) in Calvert County, Maryland, United States. The population was officially 1,666 at the 2000 census, although residents of the Chesapeake Ranch Estates-Drum Point community also use the Lusby zip code designation, making Lusby in fact a much larger community. The Calvert Cliffs Nuclear Power Plant, and a compressed natural gas plant run by Dominion Resources, are both nearby. Dominion Cove Point is one of the nation's largest liquefied natural gas import facilities. A large housing development called Chesapeake Ranch Estates is nearby, as well as the tourist resort town of Solomons. Many residents commute to the Patuxent River Naval Air Station, to Andrews Air Force Base, or with difficulty to the Washington, D.C. area.
Lusby's central business district has been growing rapidly in recent years. At least three shopping centers have either been built or have been approved, bringing in new grocery stores, restaurants, and other new businesses to the Lusby area. Several new roads are also in planning stages in order to ease traffic congestion to and from the Chesapeake Ranch Estates-Drum Point communities.
Lusby has one public high school, Patuxent High School, which opened in 1996. Patuxent's school mascot is the Panthers. There are also two public middle schools and two public elementary schools in Lusby.
