Radio jamming on the Korean Peninsula makes the border region one of the world's busiest places for radio signals. Medium wave jamming is dominant in the area including Seoul and the Korean Demilitarized Zone (DMZ). South Korea jams all radio and television broadcasts from North Korea, and until 2013 jammed all foreign broadcasts, which was ended during the Park Geun-hye administration.

North Korea jams South Korean state broadcasts and foreign shortwave broadcast services which it believes to be against the North Korean regime. These include the Korean language service of the Voice of America, Free North Korea Radio (which originates from US transmitters in Guam), Radio Free Asia, and several other services and broadcasts.
