The main line of the Southern Pacific Railway cuts the town in two. The first settler of Scott was Alexander Delhomme, who took land in the Northern part of the town. Delhomme owned the first hay-mowing machine, grit mill and cotton gin. By 1880, the train depot was completed and the town became a village. In 1907, the town was named after J. B. Scott, who was Division Superintendent of Southern Pacific Railroad. The village became a town in 1960 and the town became a city in 1990.
