Jeong Da-rae (Korean: 정다래; born December 2, 1991) is a South Korean former swimmer, who specialized in breaststroke events. She is a gold medalist in the 200 m breaststroke at the 2010 Asian Games in Guangzhou, China.
Jeong made her official debut, as a 16-year-old, at the 2008 Summer Olympics in Beijing, where she qualified for the women's 200 m breaststroke. She cleared a FINA B-cut of 2:27.78 from the Good Luck Beijing China Open. On the evening preliminaries, Jeong rounded out the semifinal field by taking the final spot in a lifetime best of 2:27.28, just half a second (0.50) faster than her entry time.

At the 2010 Asian Games in Guangzhou, Jeong picked up the women's 200 m breaststroke title in 2:25.02, beating two Chinese swimmers for the silver and bronze medals. Jeong's best effort at the Asian Games moved her up to fifteenth in the world rankings.
