Sofiya Lyskun

Sofiya Valeriivna Lyskun (; ; born 7 February 2002) is a Ukrainian-born Russian diver, medalist of the European Championships.

In December 2025, she switched her allegiance from Ukraine to Russia, resulting in the Ukrainian Diving Federation stripping her of awards won during her time with the federation.

Career She won a bronze medal in 10-meter platform synchro diving (with Valeriia Liulko) at the 2017 European Diving Championships in Kyiv and a gold in the team event (with Oleh Kolodiy) at the multi-event 2018 European Championships in Glasgow.

At age 15, Lyskun won bronze at the 10 metres platform synchro event at the 2017 European Championships in Kyiv. In 2018, she performed a difficult dive (a back two-and-a-half somersaults and one-and-a-half twists in pike) for 10 metre board that earned her the highest final round mark of any diver and the gold medal.

She qualified to represent Ukraine at the 2020 Summer Olympics in the Women's 10 metre platform event.

In late 2025, she acquired Russian citizenship and announced her intention to compete for the Russian national team. The Ukrainian Diving Federation deemed her switch "categorically unacceptable" and stripped Lyskun of her titles. According to Reuters, "Lyskun told Russian outlet Izvestia that she made the decision to switch allegiance after realising she was no longer growing under her coaches in Ukraine and that they were 'all gymnasts or trampoline athletes'".
