Prior to colonial settlement, the area comprising Louisa County was occupied by several indigenous peoples including the Tutelo, the Monacan, and the Manahoac peoples, who eventually fled to join the Cayuga Iroquois (Haudenosaunee) people in New York state under pressure from English settlers. Louisa County was established in 1742 from Hanover County. The county is named for Princess Louise of Great Britain, youngest daughter of King George II, and wife of King Frederick V of Denmark. Patrick Henry lived for some time in Louisa County on Roundabout Creek in 1764. Henry was being mentored at that time by the Louisa County magnate Thomas Johnson the representative of Louisa County in the House of Burgesses. In 1765, Patrick Henry won his first election to represent Louisa County in the House of Burgesses. At the end of the eighteenth century and in the early nineteenth century, numerous free mixed-race families migrated together from here to Kentucky, where neighbors began to identify them as Melungeon.

The Virginia Central Railroad was completed through Louisa County in 1838–1840. During the Civil War, it was an important supply line for the Confederate armies. As a result, several significant cavalry actions took place in the county, particularly one fought at Trevilians in 1864.

The Twin Oaks Community is one of the country's oldest secular communes, established by its first eight members in 1967. This was part of a national movement among numerous young people to "get back to the land" and live in more simple ways based in community. Louisa is also home to the Acorn Community, a rural, cooperative, income sharing community on about 80 acres, founded in 1993 by one of the founding members of Twin Oaks, Kat Kincade. Another newly forming community as of 2011 is the Living Energy Farm, a 'neo-Amish' farm, where no fossil fuels will be used but new technologies such as solar will be embraced. Louisa is becoming a hub of cooperative rural communities.

Lake Anna, a 13,000-acre (53 km2) artificial lake, and the associated North Anna Nuclear Generating Station were built by Virginia Power in the 1970s. In recent years the predominantly rural county has grown because of retirees' settling near Lake Anna, and because of its convenient location for commuters. It is an hour's drive or less from Richmond, Fredericksburg and Charlottesville.
