Chickasha was founded by Hobart Johnstone Whitley, a land developer, banker, farmer and Rock Island Railroad executive.

From 1910 to 1927, the town was served by the Chickasha Street Railway, the town’s own electric trolley system.

In 1908, the Oklahoma Industrial Institute and College for Girls was established in Chickasha. A local rancher named J. B. Sparks donated land for the school in memory of his daughter, Nellie.

It became coeducational in 1965, and was renamed the Oklahoma College of Liberal Arts. It was renamed again in 1975 as the University of Science and Arts of Oklahoma.
