Laurel is a city in northern Prince George's County, Maryland, in the United States, located midway between Washington, D.C., and Baltimore on the Patuxent River. Founded as a mill town in the early 19th century, the arrival of the Baltimore & Ohio Railroad in 1835 expanded local industry and later enabled the city to become an early commuter town for Washington and Baltimore workers.
