Philomont is an unincorporated community in western Loudoun County, Virginia. The name is derived from the Greek word philo meaning "beloved" and the French word mont or "mountain"; Philomont means "Beloved Mountain."
The village was established in the 19th century by Quakers. Minor skirmishes occurred in the area during theCivil War and troops from both sides routinely moved through Philomont. The famed Confederate irregulars "Mosby's Raiders" (also known as Mosby's Rangers) were active in the area throughout the war. Philomont lies within the Mosby Heritage Area. Mosby's Rangers never officially surrendered to the victorious Union forces but instead disbanded and thus remain undefeated.
