Belarus in the Eurovision Song Contest 2021

Belarus was set to be represented at the Eurovision Song Contest 2021. The Belarusian participating broadcaster, the Belarusian Television and Radio Company (BTRC), internally selected Galasy ZMesta as its representative, initially with the song "Ya nauchu tebya (I'll Teach You)", but the entry was deemed ineligible to compete by the European Broadcasting Union (EBU) due to violation of the contest's rules against political entries. After their replacement entry "Pesnya pro zaytsev (Song About Hares)" was also deemed ineligible, BTRC was disqualified from the contest on 26 March 2021. This was the first time Belarus was absent from the contest since their debut in 2004. Belarus was originally set to compete in the first half of the first semi-final on 18 May 2021.
