Paeonian Springs is an unincorporated community in Loudoun County, Virginia, United States.

It was originally developed as a resort town for citizens of Washington, D.C. trying to escape the city in the summer.

[4] When developers advertised the town upon its completion they said it had "excellent water, mountain air and magnificent scenery".

This happened for a number of reasons including: the loss of the boardwalk, mill, and church; the Pure Food and Drug Act's passage; and the discovery of antibiotics.

Twenty years later in 1988, the Washington and Old Dominion Trail, built on the old railroad's right-of-way, was extended through Paeonian Springs to Purcellville, Virginia.
