The land for the townsite of Speareville was deeded by the Santa Fe to the Arkansas Valley Town Company in March, 1873, and was surveyed and platted. The town was named for Alden H. Speare, railroad director and president of the town company. The city name appeared as both Spearville and Speareville in the early days.
