Cornelia Oschkenat, (née Riefstahl; born 29 October 1961) is a German former track and field athlete who represented East Germany.

Later that year at the World Championships in Rome, she won bronze in the 100 m hurdles behind Zagorcheva and East German teammate Gloria Siebert, but ahead of Donkova, who was fourth.

A medal favourite for the 1988 Seoul Olympics, she pulled a muscle midway through the final and limped over the line in eight place.

In 1990, she finished fourth at the European Championships in Split in what would be her eighth consecutive (and final) year ranked in the world top ten (on time and merit).

She represented a united Germany at the 1991 World Championships in Tokyo but was eliminated in the heats and retired at the end of that season.
