The KRDK-TV mast is a television transmitting tower 3.5 miles (5.6 km) northeast of Galesburg in Traill County, North Dakota, United States. It was completed in 1966 and is used by KRDK-TV (formerly KXJB-TV), which is licensed to Valley City, serving the Fargo and Grand Forks TV markets.
At 2,060 ft (627.9 m), it is currently the tallest structure in the United States, the second-tallest structure in the Western Hemisphere and the seventh-tallest structure in the world. It stands 72.8 ft (22.2 m) taller than the nearby KVLY-TV mast in Blanchard, North Dakota, which was previously 3 ft (0.9 m) taller until the removal of a VHF antenna reduced its height in 2019.
