Park Sang-in (Hangul: 박상인, born 15 November 1952) is a former South Korean footballer and football manager who manages Korea National League club Busan Transportation Corporation. His sons Park Hyuk-soon and Park Seung-min are also footballers.
Park began his career at Changnyeong Middle School at the age of 13. He went through Dongnae High School, graduating in 1972. In the same year he joined the Commercial Bank of Korea. One year later, he joined the army in order to fulfil his military service.
In 1981, he had trials for Dutch club, Feyenoord, receiving a favorable response from the club. However, the contract foundered due to an objection of the player's labor union. In July 1981, he signed a contract with Bundesliga club MSV Duisburg for 1 year. He played only two league games though, due to a thigh injury.
After retiring from club football, he was appointed as his alma mater's football team manager from 1988 to 2001. In the middle of the term, in 1992–1993, he managed the South Korea U20 team, going to the 1993 FIFA World Youth Championship. The South Korean youth team finished unbeaten, with three draws. From 2006, he has managed newly formed Busan Transportation Corporation. In 2009, he went to the 2009 East Asian Games as the South Korea team manager.
