Ekaterini Thanou

Ekaterini Thanou (Greek: Αικατερίνη Θάνου, [ekateˈrini ˈθanu]; born 1 February 1975), also known as Katerina Thanou, is a Greek former sprinter. She won numerous medals in the 100 metres, including an Olympic silver medal at the 2000 Summer Olympics in Sydney, Australia, while she was the 2002 European champion in Munich, Germany. She had also been crowned world and European champion in the 60 metres at the indoor championships.

In 2007, Marion Jones, who won in the 100 metres at the 2000 Olympics leaving Thanou in the second place, admitted that she had used steroids and her gold medal was withdrawn by the International Olympic Committee, but was not reallocated to Thanou because she was also involved in doping.

She was named the Greek Female Athlete of the Year, for the years 1995, 2000, 2001 and 2002.
