The attack on the Sui-ho Dam was the collective name for a series of mass air attacks during the Korean War on thirteen hydroelectric generating facilities by United Nations Command air forces on June 23–24 and June 26–27, 1952. Primarily targeting the hydroelectric complex associated with the Sui-ho Dam in North Korea, the attacks were intended to apply political pressure at the stalled truce negotiations at Panmunjeom.

Heavily defended by Soviet Air Forces and major anti-aircraft guns, the hydroelectric targets were subjected to attacks totaling 1,514 sorties. These were conducted jointly by fighters and fighter-bombers of the United States Air Force, United States Navy, United States Marine Corps, and South African Air Force, the first time in 21 months that the separate air arms had worked together on a massive scale. The attack on the facilities was followed seventeen days later by another series of large-scale joint attacks on the capital city of Pyongyang.

The attacks succeeded in permanently destroying 90% of the facilities struck and completely knocked out power in North Korea for two weeks, as well as reducing available power to northeast China by 23%. North Korea, however, built new facilities but did not restore its previous capacity until after the armistice in 1953. Their effect on the truce talks was also nil, as highly publicized repercussions in both the UK and the United States Congress undermined their impact.
