The land for the townsite of Spearville 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. Spearville's first permanent residents were the Santa Fe section foreman, Jonas Stafford, and his family. Stafford was stationed at this particular watering spot beginning January, 1875. Stafford's wife and daughters opened an eating house, mainly for the accommodation of the section hands. The first post office in Spearville was established in June, 1877. Toward the end of October 1892, Spearville was the site of the second robbery of the Bill Doolin Gang, which had been formed in the aftermath of the Dalton Gang's demise in Coffeyville, Kansas. The Ford County Bank was robbed of $1,697 by Doolin and two members of his gang. One of the outlaws, Ollie Yantis, was soon tracked down and killed by a posse.
