WKRU (106.7 FM) is a classic rock radio station licensed to Allouez, Wisconsin, United States and serving the Green Bay area.

The station began broadcasts in December 1996, when Jack LeDuc resurrected the WJLW call letters and its country music format one year after selling its previous home at 95.9 FM.

On December 9, 2010, WZNN changed its call sign to WKRU, rebranded as "KRUZ @ 106.7," and adopted a new adult album alternative format.

The format of "KRUZ" (pronounced on-air as "cruise") was similar to that of stations in Madison (WMMM-FM) and Chicago (WXRT-FM).

The holiday music lasted until 6 p.m. on December 25, when classic rock returned to the frequency, this time under the "106.7 The Big Dog" branding, with "Move it On Over" by George Thorogood and the Destroyers being the first song played (which was preceded by The Singing Dogs' version of "Jingle Bells," a hint of the new format's branding).
