Yekaterina Vladimirovna Dyachenko (Russian: Екатерина Владимировна Дьяченко, also known as Ekaterina Diatchenko, born 31 August 1987) is a Russian former sabre fencer.[1] Dyachenko represented Russia at the 2008 Summer Olympics in Beijing, where she competed in two sabre events.
She is the daughter of fencing coaches Vladimir and Natalya Dyachenko and the sister of Aleksey Dyachenko, who won the bronze medal as a member of the Russian team in the men's team sabre at the 2004 Summer Olympics in Athens, Greece.
In the women's individual sabre at Beijing 2008, Dyachenko first defeated Japan's Madoka Hisagae in the table of 32, before losing out her next match to Ukraine's Olena Khomrova, with a sudden death score of 14–15.[2] Few days later, she joined with her fellow fencers and teammates Ekaterina Fedorkina, Elena Nechaeva and Sofiya Velikaya for the women's team sabre. Dyachenko and her team won the fifth place match against the Polish team (led by Aleksandra Socha), with a total score of 45 touches.[3]
