Tatyana Aleksandrovna Navka (born April 13, 1975 in Dnipropetrovsk, Ukrainian SSR) is a Russian ice dancer who has also competed for the Soviet Union and Belarus. She is the 2006 Olympic Champion with partner Roman Kostomarov.
Navka originally skated for the Soviet Union with Samuel Gezalian. Following the fall of the Soviet Union, Navka and Gezalian began skating for Belarus. They placed 11th at the 1994 Winter Olympics. When that partnership fell through, Navka partnered with Nikolai Morozov, with whom she competed at the 1998 Winter Olympics, also for Belarus.
Navka left Morozov in 1998. She then partnered with Roman Kostomarov and began competing for Russia. After taking a year off after the birth of her daughter, Navka began competing in earnest. Nakva and Kostomarov won the World Championship in 2004 and 2005, as well as the European Championships. They are the 2006 Olympic champions in ice dancing.
Navka is married to Alexander Zhulin. They have one daughter, Sasha, born in 2000. She was briefly married to Nikolai Morozov, so she could obtain citizenship for Belarus.
Navka took part in TV projects of Channel One Russia: Stars On Ice (winner in couple with actor Marat Basharov) and Ice Age (runner-up in couple with actor Ville Haapasalo). In the 2008/2009 season of Ice Age she again was runner-up, partnered with actor Vadim Kolganov.
In September 2008 Navka together with professional dancer Alexander Litvinenko took part in Eurovision Dance Contest 2008.
