Toone is located in former Chickasaw country. The first Europeans to visit the area arrived on flatboats via the Hatchie River as early as 1725. By 1830 the community was populated enough that it was included in the United States census. In 1856, Toone developed into a railroad town with businesses opening up around the railroad. Brick manufacturing became the major industry, and many homes still have original Toone bricks in their architecture. During the Civil War, the town served as an encampment for the Union Army and saw one small skirmish for rail line control.
