Park Sang-young (Korean pronunciation: [pak̚.s͈aŋ.jʌŋ] or [pak̚] [saŋ.jʌŋ]; born 16 October 1995) is a South Korean right-handed épée fencer, three-time team Asian champion, 2021 team Olympic bronze medalist, and 2016 individual Olympic champion.

He nearly had to give up the sport as his family could not afford the expensive equipment but financial aid from a non-profit charity and his admission into Gyeongnam Physical Education High School [ko], a public school, allowed him to continue to fencing.

Dubbed a "monster rookie", he made headlines by narrowly defeating veterans Kweon Young-jun and Jung Jin-sun.

He sustained a knee injury while fencing against Pavel Pitra of the Czech Republic in the table of 16 at the March Grand Prix in Budapest, Hungary.

He returned to competition a year later, winning a bronze medal in the Vancouver world cup in February 2016.
