Jeong Seung-hwa (정승화, 鄭昇和; 27 February 1929 – 12 June 2002) was a South Korean general officer, and the 22nd Republic of Korea Army Chief of Staff. He was at Gungjeong-dong, site of the assassination of President Park Chung-hee, when it took place in 1979.
He joined the Korean Army as a conscript in the 17th Regiment and fought at the Battle of Busan Perimeter. He later went to the Korea Military Academy and was commissioned as a Lieutenant in the 26th Infantry Regiment in 1950, where he later commanded in the early 1960s. He then commanded a Mechanized Brigade and an Infantry Division, before being appointed as Commander of II Corps in 1976, and as Army Chief of Staff in 1978.
After President Park's death, Jeong ruled South Korea as the chief martial law administrator. He plotted to exclude political soldiers such as Hanahoe. As a result, Hanahoe's members such as Chun Doo-hwan and Roh Tae-woo committed the Coup d'état of December Twelfth and arrested Jeong. Jeong was unjustly accused of the assassination of Park and tortured.
Jeong regained his impaired reputation in 1997, 17 years after the coup d'état. He died in 2002.
