About Knoxville

Knoxville sits in southeastern Johnson County near Lake Dardanelle, where U.S. 64 and Interstate 40 cross the Arkansas River Valley. It began as a railroad town, but the ground beneath it was already part of a much older human landscape; rock art in Johnson County points to deep Indigenous history, and the valley was once hunting territory for the Osage before later treaties moved Cherokee communities west. In the nineteenth century, Thomas May’s bottomland supported crops, a sawmill, stores, and an ice plant before the railroad put a depot nearby.

The name Knoxville arrived after M. H. Hobbs bought land from May, took over the depot business, and platted a town in 1877. Cotton, fruit, timber, gins, and sawmills gave the place work; fires and tornadoes left their mark on its churches and business blocks. When Lake Dardanelle formed behind a new dam in 1965, fishing and lake travel added a new draw, and Interstate 40 kept the old corridor busy. Knoxville today has the feel of a small crossroads with a long memory: rail lines, highway traffic, river-valley crops, and lake country all meet here.
