Dunn Loring (archaic "Dunn-Loring"), the earliest platted subdivision in Fairfax County and possibly the Commonwealth of Virginia, was founded in 1886.

General William McKee Dunn and his wife Elizabeth Lanier Dunn purchased about 600 acres (2.4 km2) located on the Washington, Ohio and Western Railroad, now the Washington and Old Dominion Regional Trail, from L. B. Clarke and his wife on June 8, 1886.

The Loring Land and Improvement Company built a railroad station and a post office, but shortly thereafter General Dunn died, and the development stagnated.

In 1912, Fairfax Shield McCandlish bought out the interests of the developers, consolidated parcels, and subdivided the land into its current platting.

Following World War II, the area began to develop as part of Metropolitan Washington, D.C.[4] Up until the mid-1990s, large portions of the land (mainly between Lee Hwy and Gallows Rd.)
