"Tennessee Flat Top Box" is a song written and recorded by American country music singer Johnny Cash.

The song is a story of a little boy aspiring to be a country singer, who starts his career at a local cabaret in a South Texas border town.

He becomes so popular that girls "from there to Austin" would secretly leave home and pawn jewelry for money to make the trip to hear him play, and "all the girls from nine to ninety, were snapping fingers, tapping toes, and begging him: 'Don't stop.'"

[5] Rosanne Cash recorded the song at the suggestion of her then-husband, fellow country singer Rodney Crowell.

A version was made available to download on January 4, 2011, for use in the Rock Band 3 music gaming platform in both basic rhythm, and PRO mode which allows use of a real guitar / bass guitar, and MIDI-compatible electronic drum kits / keyboards in addition to vocals.
