The blockade of Wonsan, or the siege of Wonsan, from February 16, 1951, to July 27, 1953, during the Korean War, was the longest naval blockade in modern history, lasting 861 days. United Nations naval forces, primarily from the United States, kept the strategically important city of Wonsan from being used by the North Korean Navy.

The blockade diverted communist troops from the front line. North Korean artillery fired at the American fleet was mostly ineffective, and the city was heavily damaged by UN naval aircraft and warships.
