Yuliya Nikolaevna Topolnitskaya (Russian: Юлия Николаевна Топольницкая; born 2 May 1991) is a Russian theater and film actress. She gained fame in January 2016 when she appeared in the music video "Экспонат" (Exhibit) for the Russian band "Leningrad". She was born in Leningrad, Russian SFSR, Soviet Union (now Saint Petersburg, Russia). Her father Nikolay was an entrepreneur and mother, Nadezhda, was a doctor who worked in an orphanage. Yulia's mother wanted her to become a ballerina and for 12 years sent her to a ballet school. "But with the ballet it did not work out for me", - said the actress. Then the parents tried to push the girl into music - they bought her a piano. However, Yuliya did not like this hobby: she did not want to play the piano, and only used it as a shelf for her toys.

In 2014 she graduated from the Russian State Institute of Performing Arts, a workshop of Boris Uvarov. Since 2014 she has been working at the St. Petersburg Clownery Theater "Litsedei". In 2015, she participated with Aleksey Shamutilo in the project "Comedy Battle", but the pair finished on the second round.
