Waterloo is a village in Fauquier County, Virginia, in the United States, straddling the Rappahannock River at its confluence with Carter's Run.
The village has existed since at least 1749, when the decision was made to build a road from Warrenton (about 8 miles (13 km) east) to serve the growing number of farms along the river.
Eventually there was a sawmill, a clothing mill, a blacksmith, and a plan for a group of shops and factories on the Fauquier side to serve the community and the canal.
Stuart's force captured Pope's headquarters wagons and destroyed Union supplies and army material, shortly before the second battle of Manassas.
The counties of Fauquier, Culpeper, and Rappahannock all contributed to the funding, in order to enable local farmers and merchants to deliver goods to market.
