Nadia Elena Comăneci Conner (born November 12, 1961) is a Romanian retired gymnast and a five-time Olympic gold medalist, all in individual events. In 1976, at the age of 14, Comăneci was the first gymnast to be awarded a perfect score of 10.0 at the Olympic Games. At the same Games (1976 Summer Olympics in Montreal) she received six more perfect 10s for events en route to winning three gold medals. At the 1980 Summer Olympics in Moscow, Comăneci won two more gold medals and achieved two more perfect 10s. During her career Comăneci won nine Olympic medals and four World Artistic Gymnastics Championship medals.

One of the world's best-known gymnasts, Comăneci, along with Olga Korbut of the Soviet Union, displayed artistry and grace, which brought unprecedented global popularity to the sport in the mid-1970s. In 2000, Comăneci was named one of the Athletes of the 20th Century by the Laureus World Sports Academy. She has lived in the United States since 1989, when she defected from then-Communist Romania before its revolution in December that year. She later worked with and married American Olympic gold-medal gymnast Bart Conner, who set up his own school.
