Runnemede is a borough in Camden County, New Jersey, United States. As of the 2010 United States Census, the borough's population was 8,468, reflecting a decline of 65 (-0.8%) from the 8,533 counted in the 2000 Census, which had in turn declined by 509 (-5.6%) from the 9,042 counted in the 1990 Census.
Runnemede was incorporated as a borough by an act of the New Jersey Legislature on March 23, 1926, from portions of the now-defunct Centre Township, based on the results of a referendum held on April 24, 1926. The boroughs of Bellmawr, Mount Ephraim and Lawnside were simultaneously created during the same two-day period. The derivation of the borough's name is uncertain, though claims that it derives from a Native American term for "running water" have been refuted and connections to General George Meade or to "rum we need" for a nearby tavern are probably apocryphal. Sources have cited the name as coming from Runnymede, England.
According to the United States Census Bureau, the borough had a total area of 2.115 square miles (5.477 km2), including 2.057 square miles (5.327 km2) of land and 0.058 square miles (0.150 km2) of water (2.74%).
