Odenton is a census-designated place in Anne Arundel County, Maryland, United States, located approximately 10–20 minutes from the state capital, Annapolis. 

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, which contains NSA headquarters, US Cyber Command (established 2009), and the Defense Information Systems Agency (moved to Fort Meade in 2011). Odenton’s growth can also be attributed to it being centrally located between Annapolis, Baltimore, and Washington, D.C. The development has been fueled by the construction of the massive Piney Orchard development, progress in the ongoing development of Odenton Town Center, and construction of the NSA East Campus Integration Program scheduled for completion in 2028.
