Odenton is a census-designated place in Anne Arundel County, Maryland, United States, located about 10–20 minutes from the state capital, Annapolis. The population was 37,132 at the 2010 census, up from 20,534 at the 2000 census. The town's population growth rate of 80.8% between 2000 and 2010 was the greatest of any town in western Anne Arundel County. Odenton is located west of Annapolis, south of Baltimore, and northeast of Washington, D.C. In recent years, Odenton has become the fastest-growing city in the county with 2010 census numbers reporting 42% growth. This is because of its proximity to Fort George G. Meade, NSA headquarters and Annapolis, as well as its proximity to Baltimore and Washington, D.C. The development has been fueled by the construction of the massive Piney Orchard development as well as progress in the ongoing development of Odenton Town Center.
