Danylo Siianytsia[a] (born September 9, 2000) is a Ukrainian-born pair skater who represents the United States.

Siianytsia came to the United States on the invitation of his coach, Trudy Oltmanns, in 2016 on a P-1 visa and hopes to gain U.S.

"[1] Siianytsia's first pairs partner was Jasmine Wong, with whom he won the 2017 U.S. juvenile national bronze medalist.

[5] Siianytsia teamed up with Anastasiia Smirnova in mid-2018 after he found her profile on IcePartnerSearch and asked Oltmanns to arrange a tryout.

In January, Smirnova/Siianytsia won the junior title at the 2021 U.S. Championships by over 20 points ahead of silver medalists Martins/Bedard, despite Smirnova suffering a high ankle sprain on her right leg in practice the day before competition began.

They also competed on the senior level for the first time, placing ninth at the Skating Club of Boston's Cranberry Cup.

[11] Due to Vladimir Putin's invasion of Ukraine, the International Skating Union banned all Russian athletes from competing at the event.

"[14] Smirnova/Siianytsia placed third in the short program, winning a bronze small medal, their only error being Smirnova underrotating and stepping out of her double Axel.

[16] Moving to the international senior level full-time, Smirnova/Siianytsia made their Challenger debut at the 2022 CS Finlandia Trophy, where they finished in seventh place.

[17] Given two Grand Prix assignments, they were scheduled to make their debut at the 2022 Skate America but had to withdraw after Siianytsia suffered a groin injury.
