Park Sung-hyun (Korean: 박성현; Hanja: 朴成賢; born 1 January 1983) is an archer from South Korea who competed in two Olympic Games, winning three gold medals.

[3] Park began the 2004 Summer Olympics in Athens with a new women's world record for the preliminary 72-arrow ranking round, scoring 682 points (from a maximum of 720) to surpass the previous best of 679 set by Italy's Natalia Valeeva three months earlier.

[5] With teammates Lee Sung-jin and Yun Mi-jin she also set a new world record for the women's team event over 216 arrows, the three scoring a combined total of 2,030 points from a maximum of 2,160.

As the designated final shooter in the team, Park was responsible for scoring the ten points on the last arrow required to win the match.

With a combined tally of 2,004 points, Park, Yun, and Joo Hyun-jung also achieved a new Olympic record for the women's team event.

Her opponent was China's Zhang Juanjuan, who had finished the ranking round in twenty-seventh position and had earlier eliminated Park's teammates Yun and Joo en route to the gold medal match.

[12] She also felt that her loss would lighten the pressure placed on Korean archers to see victory as the only acceptable result in future competitions.

The South Korean team was dominant once more, winning the gold medal in all four recurve competitions for the first time since 1997.

[15] The 2007 Championships in Leipzig saw Park contribute to South Korea's third consecutive women's team title with Lee Tuk-young and Choi Eun-young.

She remained the only archer to achieve this feat for almost fifteen years before compatriot Ryoo Su Jung scored 1,400 points at a national tournament in South Korea in July 2019.
