Cool Zone was an Australian television series which was broadcast on community television station, C31 Adelaide in Adelaide, South Australia. The show was aimed at a wide demographic with a focus on teenagers and was hosted by M-Cool. Each episode lasted for approximately five minutes plus commercials. Cool Zone consisted of numerous segments per episode but usually a consistent subject matter and shoot location.

The program first aired in August 2005 with C31 commissioning a first season run of 24 episodes. Despite a cult following the program was axed after just four weeks and replaced by repeats of the SA Sports Show. Several Australian commercial networks expressed interest in picking up Cool Zone in 2006 but could not reach agreement with M-Cool.
