The name "Jellico" is a regional corruption of "Angelica", an herb that grows in abundance in the surrounding mountains. The name was first applied to the mountains to the west and to the mountains' main drainage, Jellico Creek, which empties into the Cumberland River near Williamsburg, Kentucky. In the early 1880s, a high quality bituminous coal was discovered in the Jellico Mountains, and with the completion of railroad tracks to the area in 1883, coal mines quickly sprang up throughout the area. The city of Jellico was initially founded as Smithburg in 1878, but changed its name to "Jellico" in 1883 to capitalize on the growing popularity of Jellico coal. The city was incorporated on March 7, 1883.
Throughout the 1890s and early 1900s, Jellico was one of the most productive coal fields in Kentucky and Tennessee. In 1906, a railroad car packed with dynamite exploded in Jellico, killing eight and destroying part of the town. The town quickly recovered, however, and many of the buildings in the Main Street area date from this recovery period. In 1999, much of North and South Main Street was placed on the National Register of Historic Places as the Jellico Commercial Historic District.
Jellico Community Hospital is the largest employer with approximately 350 employees.
On October 18, 2012, WATE television reported that Jellico was "broke" and that "city employees had not been paid."
Since 1922, Jellico has been the home of the denominational headquarters for the Church of God Mountain Assembly, a holiness Pentecostal Christian denomination.
