WCJK (96.3 FM) is a commercial radio station licensed to Murfreesboro, Tennessee and serving the Nashville metropolitan area.

It airs an adult hits radio format and is owned by Midwest Communications, Inc.[2] It subscribes to the nationally syndicated Jack FM service.

[3] The studios and offices are located on Rosedale Avenue in south central Nashville near the Tennessee State Fairgrounds arena.

At first, it was a simulcast of sister station WMTS (AM 860, now WMGC), using the initials of the owners' surnames along with the city of Murfreesboro.

It was by sheer coincidence that the call sign matched the initials of the local college, Middle Tennessee State.
