Spotsylvania County is a county in the U.S. state of Virginia. As of the 2000 census, the population was 90,395, with the Census Bureau projecting it to be 120,031 in 2008, a 32.8% increase since 2000, making it the 84th fastest growing county in the nation during this time period. Its county seat is Spotsylvania Courthouse.
The independent city of Fredericksburg is located northeast of the county but is politically separate. This county is a part of the Washington Metropolitan Area because of its vast numbers of commuters who travel north on Interstate 95 or the Virginia Railway Express (VRE) for work. Spotsylvania County was established in 1721 from Essex, King and Queen, and King William counties.
The county was named in Latin for Lieutenant Governor of Virginia Alexander Spotswood. Many battles were fought in this county during the Civil War, including the Chancellorsville, the Wilderness, Fredericksburg, and Spotsylvania Court House.
