Wilmer McLean (May 3, 1814 – June 5, 1882) was a wholesale grocer from Virginia. It is said that the American Civil War started in his front yard and ended in his front parlor.

The initial engagement on July 18, 1861 of what would become the First Battle of Bull Run took place on McLean's farm, the Yorkshire Plantation, in Manassas, Prince William County, Virginia. Union Army artillery fired at McLean's house, which was being used as a headquarters for Confederate Brigadier General P. G. T. Beauregard, and a cannonball dropped through the kitchen fireplace. Beauregard wrote after the battle, "A comical effect of this artillery fight was the destruction of the dinner of myself and staff by a Federal shell that fell into the fire-place of my headquarters at the McLean House."

McLean was a retired major in the Virginia militia, but at 47, he was too old to return to active duty at the outbreak of the Civil War. He made his living during the war as a sugar broker supplying the Confederate States Army. He decided to move because his commercial activities were centered mostly in southern Virginia and the Union army presence in his area of northern Virginia made his work difficult. He undoubtedly was also motivated by a desire to protect his family from a repetition of their combat experience. In the spring of 1863, he and his family moved about 120 miles (200 km) south to Appomattox County, Virginia, near a dusty, crossroads community called Appomattox Court House.
