Seagoville is a city in Dallas County, Texas, United States, and a suburb of Dallas. A small portion of Seagoville extends into Kaufman County. The population was 14,835 at the 2010 census. The city is located along U.S. Highway 175 and the Southern Pacific Railroad, 10 miles (16 km) from downtown Mesquite.
The town was founded in 1876 as Seago by T. K. Seago (1836–1904). The United States Post Office changed the town's name to "Seagoville" in 1910 to prevent confusion with another city in Texas called Sego.
Seagoville is fast growing and improving in economic development. Plans are in place to rebuild downtown Seagoville into a new retail area. The surrounding areas had been approved for substantial property upgrades. This project is entitled Town Center. This project was approved as a go-ahead by the Planning and Zoning Committee on December 13, 2007.

The one room log school house, which featured split-log seating, was constructed around 1867 in the area of the modern-day Heard Park. Professor J.T. Doss built a new school building in 1880. In 1909 that school was destroyed in a fire. In 1910 a new brick high school building opened on the site of what is now Seagoville Elementary School.
