The Battle of Pork Chop Hill, known as Battle of Seokhyeon-dong Northern Hill in China, comprises a pair of related Korean War infantry battles during April and July 1953. These were fought while the United Nations Command (UN) and the Chinese and North Koreans negotiated the Korean Armistice Agreement. In the US, they were controversial because of the many soldiers killed for terrain of no strategic or tactical value, although according to US sources (disputed by Chinese sources) the Chinese lost many times the number of US soldiers killed and wounded. The first battle was described in the eponymous history Pork Chop Hill: The American Fighting Man in Action, Korea, Spring 1953, by S.L.A. Marshall, from which the film Pork Chop Hill was drawn. The UN won the first battle but the Chinese won the second battle.

The UN, primarily supported by the United States, won the first battle when the Chinese broke contact and withdrew after two days of fighting. The second battle involved many more troops on both sides and was bitterly contested for five days before UN forces conceded the hill to the Chinese forces by withdrawing behind the main battle line.
