After excelling internationally in the 2006 and 2007 season, Jung competed for the South Korean swimming team in a breaststroke double at the 2008 Summer Olympics in Beijing. On the first half of a double, the 100 m breaststroke, Jung charged her way to the runner-up spot behind Italy's Roberta Panara in heat four with a steady 1:09.26, but missed the semifinals by almost a full second with a twenty-third overall placement.{{cite web|title=Swimming: Women's 100m Breaststroke Heat 4 |url=http://www.2008.nbcolympics.com/swimming/resultsandschedules/rsc=SWW031900/index.html |work=Beijing 2008 |publisher=NBC Olympics |access-date=18 January 2013 |url-status=dead |archive-url=https://web.archive.org/web/20120821032037/http://www.2008.nbcolympics.com/swimming/resultsandschedules/rsc%3DSWW031900/index.html |archive-date=21 August 2012 }} In her signature event, the 200 m breaststroke, Jung bounced back from the initial half of her specialty double to successfully grab the eleventh seed for the semifinals (2:25.95), but fell short on a berth for the top eight final by the following morning with a disappointing 2:26.83, matching her prelims position in the process.{{cite web|title=Swimming: Women's 200m Breaststroke Semifinal 2|url=http://www.2008.nbcolympics.com/swimming/resultsandschedules/rsc=SWW032200/index.html|work=Beijing 2008|publisher=NBC Olympics|access-date=18 January 2013|url-status=dead|archive-url=https://web.archive.org/web/20120821062209/http://www.2008.nbcolympics.com/swimming/resultsandschedules/rsc=SWW032200/index.html|archive-date=21 August 2012}}{{cite news|title=정슬기, 평영 200m 결승 진출 실패|trans-title=Jung Seul-ki fails to enter the 200 m breaststroke final|language=ko|url=http://www.hani.co.kr/arti/sports/sports_general/304266.html|publisher=The Hankyoreh|date=14 August 2008|access-date=3 May 2016}}
