Smithville is a city in Bastrop County, Texas, United States, near the Colorado River. The population was 3,817 at the 2010 census. Smithville is part of the Greater Austin metropolitan area.
Dr. Thomas Jefferson Gazley arrived in 1827 and set the pace of development for Smithville by building the first house and establishing the first store, which served incoming settlers and the friendly Lipan and Tonkawa Indians. He later served in the Mexican government and helped write the Texas Declaration of Independence and the first Constitution, and became a true Texas hero.
William Smith's family arrived several years after Dr. Gazley. They also owned a store and were early influences on the area, including the naming of Smithville where about seventeen families lived on the south bank of the Colorado River.
Local businessman, Murray Burleson, persuaded the approaching railroad to erect a Terminus here and the TB&H steamed through in 1887.
