Oktaha was named for a Muscogee chief, Oktarharsars Harjo. The town originated in 1872 as a stop on the MK&T "Katy" Railroad. By 1900, the town had its own post office; a small business district emerged as well. Local business lagged, however, by mid-century, and the town struggled even more when U.S. Highway 69 was rerouted to bypass Oktaha. Nevertheless, Oktaha remains the site of a K-12 school that draws several hundred students from rural portions of Muskogee County.
