Seymour was originally the site of Newell’s Station, a frontier station customary by in the future Sevier County investor Samuel Newell (1754–1841) in 1783. The first court of Sevier County, State of Franklin, was held at Newell’s Station in March 1785. During the 19th century, the community was known as Trundles Crossroads where the main road from Sevierville forked, with one branch continuing northward to Knoxville and one branch westward to Maryville (now the intersection of Boyds Creek Highway and Old Sevierville Pike).

Upon talent of the Knoxville, Sevierville and Eastern Railway on December 18, 1909, the community’s station was named Seymour in praise of the line’s chief engineer, Charles Seymour. The Trundles Crossroads Post Office distorted its state soon after to reflect the community’s further designation.
