Choi Eun-sung (born 5 April 1971) is a South Korean former professional footballer who last played for Jeonbuk Hyundai Motors. He spent 15 seasons as the goalkeeper with Daejeon Citizen.

He played for the South Korea national football team and was a participant at the 2002 FIFA World Cup.

He was the first goalkeeper to score in the AFC Champions League, in a match against Monte Carlo on 9 October 2002. Daejeon Citizen went on to win the match 5–1.^{[citation needed]}

In February 2012, just before the 2012 league campaign, Choi requested to extend his contract with Daejeon for one more year, but the board rejected his proposal and he was forced to leave the club and become a free agent. On 23 March 2012, Choi joined Jeonbuk Hyundai Motors on a one-year deal. While at Jeonbuk, Choi sportingly scored an own goal on purpose during a match against Seongnam, after team-mate Lee Dong-gook accidentally scored while attempting to return the ball to Seongnam's goalkeeper; Seongnam won the match 2–1.^[1]
