Julia Nikolayevna Obertas, married name: Horak (Russian: Юлия Николаевна Обертас, Ukrainian: Юлія Обертас; born 19 June 1984) is a former pair skater who represented Ukraine until 2000 and then Russia until the end of her career.

At the 2000 World Championships, Obertas/Palamarchuk were 10th after the short program but during the free skate Palamarchuk caught an edge (right skate) while executing an overhead lift with Obertas – she was uninjured in the resulting fall but he hit his head on the ice.

[1] Obertas moved to Russia as her mother had remarried and the family decided to settle in Saint Petersburg.

[5] In the summer of 2000,[6] Obertas teamed up with Alexei Sokolov and began to represent Russia, coached by Ludmila Velikova and Nikolai Velikov.

[1] Obertas had begun dating another one of the Velikovs' students, Sergei Slavnov, and in August 2003, they decided to skate together, switching coaches to Tamara Moskvina who also worked at Yubileyny.

[1] At the 2004 Skate America, shortly after Tatiana Totmianina's accident, Obertas fell out of an overhead lift, a hand-to-hand lasso lift, but Slavnov managed to catch her to prevent her head hitting the ice.

[7] The pair won bronze at 2006 Trophée Eric Bompard and finished 6th at 2006 NHK Trophy.
