Springfield is a census-designated place (CDP) in Fairfax County, Virginia, United States. The Springfield CDP is recognized by the U.S. Census Bureau with a population of 30,484 as of the 2010 census.
Springfield was founded in 1847 around the Orange and Alexandria Railroad's Daingerfield Station; this is today theBacklick Road Virginia Railway Express station, located off Backlick Road. The station was named for "Springfield Farm", owned by Henry Daingerfield, an Alexandria businessman who sat on the railroad's board of directors. The post office was completed sometime after 1851. It was in existence at the time of the American Civil War, being the site of a skirmish on October 3, 1861 and a Confederate raid on August 3, 1863. The station served as the first Springfield Post Office from 1866 to 1868.In 1877, Richard Moore petitioned for a post office, which he named Moor; it was located about a little over a mile south of the station, near the intersection of Fairfax (now Old Keene Mill) and Backlick roads. The post office name was changed in 1881 to Garfield to honor the late President James A. Garfield, who had been assassinated that year. In 1907, the Garfield post office closed and a new postal station named Corbett (after the then-landowner) opened back at the railroad station.The name "Springfield" was reinstated for good on June 27, 1910, although the name Garfield continued to appear on maps at least through the 1930s. The post office was moved to a new site in 1933.
