Eleni Ioannou (13 January 1984 – 24 August 2004) was a member of the Greek judo team. She was due to compete at the 2004 Summer Olympics. On 7 August 2004 she jumped from a third floor balcony of an apartment building, then spent the next 17 days in critical condition until she died.
The suicide incident occurred shortly after an episode with Eleni's boyfriend, Giorgos Chrisostomides. On August 9, he jumped from the same balcony, but recovered from his injuries.
