The original name of Glade Spring derives from the Indian word Passawatami which means "this is the place". According to early records, near the town is a field where Native American tribes held a type of Olympics in the fall, with athletic competitions, dancing and socializing. The Porterfield family, who arrived about 1760, were some of the earliest permanent settlers. During its first years, the town was called Glade Spring Depot to differentiate it from the community centered on Glade Spring Presbyterian Church, two miles to the southwest on the old stage road, now U.S. Route 11. The post office was moved from Old Glade to Glade Spring Depot in 1856 due to the arrival of the railroad. The Civil War slowed its growth, and local men made up a military unit called The Glade Spring Rifles. Federal and Confederate troops passed through the town several times, and cannon emplacements can still be seen just outside Glade Spring on the road to Saltville. Although a few new buildings were constructed before the Civil War, most of the town's growth occurred rapidly in the decade after the war. With the railroad access, Glade Spring turned into a prime shipping yard for produce, livestock and other local goods. An Abingdon newspaper first took note of the "stirring, thriving, wide-awake community" in 1870. By the time Glade Spring was incorporated in 1875, there were 31 houses, six stores, two hotels, and a Masonic Hall. Virginia Intermont College was located in Glade from 1884 to 1892, before it moved to its location until its closure in Bristol. After the passenger train service discontinued, the town's growth slowed, although it still receives freight service from Norfolk Southern railway. The train tracks of the 8.91 "Saltville Branch", which connected to Saltville via a junction from the main line at Glade Spring, have been removed and replaced with a hiking and biking trail called the "Salt Trail". In the early morning hours of April 28, 2011, an EF-3 tornado hit parts of the Glade Spring area, killing three people and injuring 50 others. Another person died in a traffic accident during the storm. The system that hit Glade Spring was part of the 2011 Super Outbreak that caused hundreds of deaths and widespread damage all across the South. Brook Hall and the Glade Spring Commercial Historic District are listed on the National Register of Historic Places.
