National Barn Dance, broadcast by WLS-AM in Chicago, Illinois starting in 1924, was one of the first American country music radio programs and a direct precursor of the Grand Ole Opry.

It also set the stage for other similar programs, in part because the clear-channel signal of WLS could be received throughout most of the Midwest and even beyond in the late evening and nighttime hours, making much of the United States (and Canada) a potential audience. The program was well-received and thus widely imitated.
