Lacey Spring is an unincorporated community located in Rockingham County, in the U.S. state of Virginia.

[2] Two historical markers in the area commemorate a cavalry skirmish during the U.S. Civil War.

On 21 December 1864, part of the 3rd Cavalry Division under the command of Union Brevet Colonel George Armstrong Custer came under attack from Confederate Major General Thomas L. Rosser’s Laurel Brigade, forcing Custer to withdraw to the north.

Custer and Rosser were friends and members of the class of 1861 at West Point, and may have briefly been roommates.

Rosser resigned from West Point in May 1861, two weeks prior to graduation, to join the Confederacy.
