Belarus in the Eurovision Song Contest 2021

Belarus had originally planned to participate in the Eurovision Song Contest 2021 in Rotterdam, Netherlands. They internally selected Galasy ZMesta as their 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 "Pesnyu pro zaytsa (Song About Hares)" was also deemed ineligible, Belarus was disqualified from the contest on 26 March 2021. This was the first time Belarus was absent from the contest since the country's debut in 2004. Belarus was originally set to compete in the first half of the first semi-final on 18 May 2021.
