Corina Georgiana Ungureanu (born 29 August 1980 in Ploieşti) is a world-class Romanian artistic gymnast who competed internationally between 1993 and 1999. She was a member of two gold medal-winning World Championships teams and was the 1998 European Champion on the floor exercise.

Ungureanu began gymnastics at the Petrolul Ploieşti club in her hometown of Ploieşti, but spent the major part of her career training in Bucharest under Leana Sima. In the national training center in Deva, she was coached by Octavian Belu. Ungureanu's first international assignment was a junior dual meet between Romania and Germany, where she placed first with her team and eighth in the all-around. She resurfaced on the international scene again in 1996, when she won the all-around title at the EcoAir Cup. She did not compete in the 1996 Olympics, but was a member of the gold medal-winning Romanian teams at the 1997 and 1999 World Gymnastics Championships. She was forced to retire in 1999 due to a spinal cord injury.
