Olga Nikolayevna Jarkova (Russian: Ольга Николаевна Жаркова; born January 11, 1979 in Moscow, USSR) is a Russian curler. Jarkova has been curling for Russia internationally since 1999, when she threw fourth stones for Nina Golovtchenko at the World Junior Challenge where they won silver. She threw third stones that year at a disappointing last place finish in the World Junior Curling Championships. After this, she was back to throwing fourth stones. At the 2001 European Curling Championships she became skip of the Russian team. This move eventually paid off, as the team won the gold medal at the 2003 Universiade. They defeated Krista Scharf of Canada in the final. Jarkova remained as the Russian skip until 2005 when she was the team's alternate at the 2005 World Women's Curling Championshi
