Lovettsville is a town in Loudoun County, Virginia, United States. The population was 853 at the 2000 census.
Following the 1722 Treaty of St. Albans which established the Blue Ridge Mountains as the buffer between Native Americans and white settlers, German immigrants began arriving in the northern Loudoun Valley to farm the rich topsoil. They established several villages, many constructed of log and wooden buildings, and began to expand their land holdings. Lovettsville was then called The German Settlement.
In 1820 David Lovett subdivided his property into quarter-acre "city lots." As a result of the ensuing construction boom, the town was called Newtown. In 1828, the town was again renamed Lovettsville. In 1836 the Virginia General Assembly established Lovettsville as a town, but the town was not fully incorporated until 1876.
