Iwo Jima LORAN-C transmitter was a LORAN-C transmitter at Iwo Jima, Japan of Grid 9970 at 24°48′8″N 141°19′32″E / 24.80222°N 141.32556°E / 24.80222; 141.32556. The Iwo Jima LORAN-C transmitter had a transmission power of 4 megawatts, which is more than the most powerful broadcasting stations. The Iwo Jima LORAN-C transmitter had a 411.5 metre (1350 ft) tall guyed mast, which was built in 1963. It collapsed in 1965 at repair trial of a defective eyebolt in a backstage insulator. The collapsing tower killed six people and also destroyed the transmitter building.

The tower was later replaced by another tower of the same height. On September 29, 1993 the Iwo Jima LORAN-C transmitter was transferred from the U.S. Coast Guard to the Government of Japan. In 1994, the transmitter was shut down, and its tower was demolished. After closing the Iwo Jima transmitter, the service had been provided by the Niijima LORAN-C transmitter. The Niijima transmitter was shut down on February 1, 2014.
