Gladewater was founded by the Texas and Pacific Railway Company in 1873 on land bought from Jarrett Dean and Anderson White. A community called St. Clair, 2 miles (3 km) to the east, moved to Gladewater when the railroad announced that the only mail stop in the area would be there; residents from Point Pleasant, also bypassed by the railroad, moved to Gladewater. The first post office at Gladewater was established on August 22, 1873. The town's name probably originated from its proximity to Glade Creek, a tributary of the Sabine River that rose in a rather barren region called the Glades.
