KZJK (104.1 FM) is a radio station broadcasting the adult hits "Jack FM" format in the Minneapolis-St. Paul region of Minnesota. The station is owned by CBS Corporation through the radio subsidiary CBS Radio.

Currently, the station's main transmitter is rated at 89,000 watts effective radiated power and is located on KMSP-TV's tower in the suburb of Shoreview, with the city of license in the suburb of St. Louis Park. An auxiliary transmission facility is located atop the IDS Center in downtown Minneapolis (where studios for the station are located, though separately).

The 104.1 MHz frequency in the Twin Cities area signed on in 1962. For much of its early history, the station was KRSI-FM, paired with a sister AM station with the same call letters. The two stations simulcast with each other on and off through much of their existence, and finally separated when the AM station was sold separately in 2005.

Until the mid-1990s, the station was hampered by a badly located tower. Although they were licensed to the west Minneapolis suburb of St. Louis Park, the studios were located in Eden Prairie, while their tower was located east of the Twin Cities, in Somerset, Wisconsin. The result was a spotty signal in parts of the metropolitan area, and it would be many years until this situation was rectified.
