Nameless is an unincorporated community in Jackson County, Tennessee, United States.

One version of the name's origin holds that when residents applied for a post office, the place for a name on the application was left blank, and the U.S. Post Office Department returned the application with "Nameless" stamped on the form.

According to this version, after his first choice was rejected the official wrote to federal authorities that if his original request could not be used, he preferred for the post office to be nameless.

[8] Nameless is mentioned in the Elvis Costello song "My Dark Life" (on the album Extreme Honey) together with two other places with unusual names, Ugly, Texas, and Peculiar, Missouri.

[9] "Nameless, TN" is the eleventh track on the 2023 Old Crow Medicine Show album, Jubilee.
