Waverly was established by Steven Pavatt as a stop along the stagecoach road between Nashville and Memphis in the early 19th century. Pavatt was a fan of the author Sir Walter Scott, and named the community after Scott's Waverley Novels. When Humphreys County was created in 1803, Reynoldsburg, located northwest of Waverly along the Tennessee River, was chosen as the county seat. However, when county lands on the west bank of the Tennessee split off to become part of the newly created Benton County in 1835, the Humphreys County seat was moved to Waverly, which had become the more central location in the county. A courthouse was built in 1836, and the town was officially incorporated in 1838.
